Hiring foreign workers in Europe

Austria

Austria's sponsor-side workload sits with the employer or host institution on employer-backed work routes and the researcher permit. Job Seeker Visa cases do not have a sponsor, but Red-White-Red Card, EU Blue Card, and researcher filings all depend on the sponsor issuing the underlying offer or admission agreement, matching the route-specific paperwork to the category, and staying available for AMS or residence-authority follow-up.

Belgium

Belgium places most sponsor-backed work immigration on the Belgian employer, recognised research organisation, or Belgian group entity because over-90-day employee routes are handled through the competent region and tied to the federal residence decision. This sponsor guide covers the fixed-term single permit, EU Blue Card, researcher authorisation, and ICT permit; self-employed professional-card cases stay outside it because they do not rely on a third-party sponsor.

Bulgaria

In Bulgaria, sponsor-side work sits mainly with the employer or receiving entity on the single permit, EU Blue Card, seasonal worker, and intra-corporate transferee routes. The sponsor usually has to start the labour-market or route-specific authorization, keep the filed contract and role details consistent through visa D and residence stages, and stay available for follow-up from the Employment Agency, the Migration Directorate, or both.

Croatia

Croatia's sponsor-side workload sits with the employer or host institution on the standard residence and work permit, the EU Blue Card, the ICT permit, and research stays. The sponsor has to choose the right route, line up the contract or hosting basis with the route conditions, and handle any Croatian Employment Service or police-administration follow-up that the worker cannot satisfy alone.

Cyprus

Cyprus puts most sponsor-side work on the employer, host research organization, or Cyprus group entity. Standard employment still depends on the labour and migration chain, foreign-interest companies get a separate strategy-based channel, the Blue Card is limited to specific sectors, and ICT or researcher cases rely on route-specific corporate or hosting evidence rather than a generic employer checklist.

Denmark

Most Danish non-EU work permits are employer-backed, and the sponsor-side decision is mainly about whether the hire fits an ordinary route such as Pay Limit or a Positive List, whether the company can use Fast-Track certification, and whether the role is a genuine researcher appointment. Sponsors should expect SIRI scrutiny on Danish-standard salary and terms, route-specific evidence, and timely reporting when employment conditions change.

Estonia

In Estonia, the sponsor side is not optional admin. Employers or host institutions usually initiate the decisive step by registering short-term employment, issuing the contract or invitation, obtaining Estonian Unemployment Insurance Fund permission where required, and carrying sponsor obligations under the Aliens Act. Which sponsor workflow applies depends on whether the worker is a standard hire, Blue Card case, researcher, or intra-group transferee.

Finland

For Finland work permits, the sponsor-side work usually revolves around choosing the correct route, supplying employment terms through Enter Finland for Employers or the paper fallback, making sure salary and working conditions meet Finnish rules, and answering any later Migri requests quickly. The obligations differ by route: TTOL cases can face labour market testing, researcher cases turn on a hosting agreement, and specialist, EU Blue Card, and eligible ICT first permits can use fast track if the employer acts within the required window.

France

France makes the sponsor decide early whether the hire sits in a route with prior work authorisation or in a talent exemption. Standard salaried, seasonal, and many posting cases start with the online work-authorisation service, while the EU Blue Card, researcher, and some other talent subcategories depend on the right contract terms, hosting agreement, or employer declaration instead of a separate work permit.

Germany

Germany's sponsor-side burden sits with the employer or host institution on job-backed permits and with any employer that chooses the fast-track procedure under Section 81a. The sponsor has to issue the underlying contract or hosting basis, keep the role consistent with recognition and salary rules, and stay ready for foreigners-authority or consular follow-up.

Greece

Greece's sponsor-side burden sits heavily with the employer or host institution. Standard employment, seasonal work, the EU Blue Card, intra-corporate transfer, and researcher filings all depend on the sponsor choosing the correct route first, preparing the invitation or host-side approval file, and staying available for follow-up from the migration or labour authorities. Greece does not offer a general sponsorless work-search route in the core system covered here.

Hungary

In Hungary, sponsor-side work is unusually important because the route choice itself can depend on employer status, host-organisation category, and current nationality restrictions. Employers or host institutions are responsible not just for issuing contracts or hosting agreements, but also for route fit, Enter Hungary follow-up, and ongoing notifications when work starts, fails to start, changes, or ends. The most operationally demanding sponsor routes are guest workers, employment permits, the EU Blue Card, Hungarian Card, research, and intra-corporate transfer.

Ireland

Ireland's sponsor-side burden sits with the employer for DETE employment permits and with the accredited research organisation for hosting agreements. The sponsor has to issue the underlying contract or hosting basis, keep salary and role details aligned with the chosen route, and support the worker through any visa and registration follow-up without trying to claw application costs back from them.

Italy

Italy's sponsor-side burden sits mainly with the employer or host institution because most non-EU work routes begin with a sponsor filing through the Sportello Unico per l'Immigrazione or a protocol-based substitute communication. The big sponsor choice is whether the hire belongs in the quota-based subordinate-work track or in an outside-quota specialist route such as the EU Blue Card, research permit, or ICT transfer, because the evidence package and timing change materially by route.

Latvia

Latvia's sponsor-side burden sits with the employer or host institution that wants the worker in country. For most employer-backed cases the sponsor now works through the State Employment Agency opinion process and then files an electronic invitation or summons with OCMA, while research hosts also need the scientific cooperation agreement and NVA states that the employer assumes responsibility for compliant pay, stay conditions, and return costs where required.

Lithuania

Lithuania's sponsor-side work sits with the employer or host institution on almost every practical work route: standard employment permits, the EU Blue Card, intra-corporate transfer permits, researcher channels, and seasonal work visas all rely on a sponsor filing the mediation letter in MIGRIS and keeping the contract, salary, and role details aligned across the case. The recurring sponsor pattern is vacancy or labour-market prep where required, mediation-letter filing, and prompt reporting if the employment relationship changes.

Malta

In Malta, sponsor-side work falls mainly on the employer or host entity because the standard Single Permit, KEI, SEI, EU Blue Card, ICT, and seasonal routes all depend on a sponsor-backed contract, transfer basis, or seasonal engagement. The sponsor has to choose the correct route, meet vacancy-advertisement and salary rules where they apply, submit the file online or support the permit workflow, and keep the role details consistent until the worker has lawful authority to start.

Netherlands

Dutch sponsor-side work immigration is driven by whether the employer or host is already recognised by the IND and whether the route is a fast-track knowledge route, a researcher filing, an ICT transfer, or a labor-market-tested paid-employment case. Employers and host institutions carry the main filing burden, and recognised sponsors also take on formal information, record-keeping, and duty-of-care obligations.

Norway

Norway's sponsor burden sits mostly with the employer or Norwegian client on routes that depend on a concrete offer or assignment. Employers can in some cases file on the worker's behalf, but even when the worker files directly from abroad the employer or client often has to confirm the offer with UDI first and keep the contract terms aligned with the immigration category and Norwegian labour-law baseline.

Poland

Poland's sponsor-side burden sits with the employer or host entity that supplies the contract basis, employer attachment, or transfer package behind the worker's stay. For ordinary local hires, the sponsor usually supports either an employer-requested work permit for entry from abroad or the Appendix 1 and contract package for a combined residence-and-work filing inside Poland; research hosts and ICT receiving entities carry their own dedicated documentation tracks.

Portugal

Portugal's sponsor-side burden sits with the employer, research host, or corporate host entity on the routes that depend on a Portuguese or same-group sponsor. Standard subordinate work, highly qualified activity, the EU Blue Card, researcher permits, and ICT transfers all require the sponsor to issue the underlying contract or host document in the format the route expects, while the standalone job-seeker stage does not yet have a sponsor until employment is formalised.

Romania

Romania's sponsor-side burden sits mainly with the employer, service beneficiary, or host institution that starts the file. In most non-EU work cases the sponsor obtains the work or posting permit first, keeps the contract and corporate documents aligned with the selected route, and then hands the worker the permit or hosting basis needed for the visa and IGI residence stages.

Slovakia

Slovakia's sponsor-side burden sits with the employer or host institution on nearly every useful non-EU work route. The sponsor usually has to report the vacancy or trigger the labour-office step, issue the contract or hosting agreement that defines the route, and stay ready to answer police or labour-office follow-up if the file stalls.

Slovenia

Slovenia's sponsor-side process sits with the Slovenian employer, host institution, or associated group company on the routes that depend on an external sponsor. Standard single permits, the EU Blue Card, research permits, and intra-corporate transfer cases all require the sponsor to issue the underlying contract or hosting basis, coordinate the filing channel, and stay available for administrative-unit and Employment Service follow-up.

Spain

Spain's sponsor-side workflow splits between two systems. Ordinary employee and seasonal permits stay in the general foreigners regime, where the employer handles labour-market and company paperwork through the competent immigration office or Mercurio. Highly qualified, researcher, and intra-company transfer cases move into the Law 14/2013 UGE channel, where sponsors file electronically and carry more of the structured corporate and route-justification burden.

Sweden

Sweden's sponsor-side workload sits heavily with the employer or research host. The Swedish side usually has to start the application, keep the vacancy advertisement, contract, insurance package, and union-comment step aligned with the chosen route, and then stay ready for Migration Agency follow-up and post-hire tax-reporting obligations.

United Kingdom

UK sponsor-side immigration work is front-loaded: the employer or host usually needs the right sponsor licence, a role that genuinely fits the chosen route, and paperwork that stays aligned with the Immigration Rules before a worker can file. The main sponsor-backed tracks are Skilled Worker, Health and Care Worker, and Senior or Specialist Worker, while Global Talent is mostly unsponsored but can still depend on a research host or named academic appointment for some academic endorsement paths.
