EU membership changes the equation
Most of the countries EuroDevHub covers — Poland, Czechia, Slovakia, Hungary, Slovenia, Croatia, Lithuania, Latvia, Estonia, Bulgaria, and Romania — are EU members, and all but Bulgaria and Romania are also in the Schengen area. If you already hold an EU passport, you can generally move and work in any of them without a visa or work permit.
Non-EU candidates need a national work permit and residence permit, or the EU Blue Card, before starting work. Serbia and Montenegro sit outside the EU, so their immigration processes run entirely on national rules rather than EU-wide frameworks.
The EU Blue Card, in short
The EU Blue Card is a work-and-residence permit designed for skilled non-EU professionals with a job offer above a salary threshold set by each country. It's faster to obtain than a standard work permit in several CEE countries and often comes with an easier path to long-term residency and family reunification.
Thresholds, processing times, and exact eligibility criteria change country by country and year by year, so always confirm current figures with the employer's HR/legal team or the national immigration office rather than relying on older sources.
National tech-specific visas
Several countries in the region run streamlined tracks specifically for tech workers and startups — for example, Poland's IT-focused fast-track permits, Estonia's Digital Nomad Visa and startup visa program, and similar schemes elsewhere. These usually mean shorter processing times and lighter paperwork than the standard work permit route, but availability and terms shift, so ask the employer which track they intend to sponsor you under.
Questions to ask before accepting an offer
Who covers the visa/permit application fees and legal costs — you or the company?
Does the offer include relocation support (flights, temporary housing, or a relocation allowance)?
What's the expected timeline from signed offer to your legal start date?
Is the permit tied to this specific employer, or portable if you later switch jobs?
