How to find out about an entry or exit ban
Decisions banning entry into Ukraine or restricting exit can be taken by the State Migration Service, the State Border Guard Service, the Security Service and the National Police. Getting complete information from all of them on your own is difficult, especially from abroad.
The most reliable way is an attorney's request. The attorney receives an official reply that you can use to plan your trip or to challenge the ban.
You can order a request online in the Attorney requests online section. More about the grounds for a ban: Find out if there is a ban.
