The right to work: You can do this under conditions identical to those of Romanian citizens. If you are an Ukrainian citizen, you have entered Romania legally and you have not requested a form of protection (for example asylum), you can work without having a job permit. You will not need to obtain a visa to get a job.
If you want to work in a field in which you have experience or for which you have studied and do not have the necessary documents (diplomas, certifications, attestations) you will give a statement on your own responsibility that you have had training or experience in the field (one one of the requirements is not to have active criminal acts).
This declaration is valid for 12 months, but can be extended for 6 months or 1 year, during which time you will have all the rights and obligations provided by the labor law. If you have studied medicine, dentistry, veterinary medicine, pharmacy, architecture or any liberal profession and you want to work in Romania, you must have the necessary documents.
Also, the Ukrainian citizens who arrived in Romania due to the armed conflict can benefit from measures to stimulate employment, as well as protection within the unemployment insurance system, under the conditions provided by law for Romanian citizens, provided they register with the agencies. for the employment of the county, respectively of the Bucharest municipality.
