Poland's invitation letter validity. [26]
when i exit from the piland air port. They will deport me or not?
1. They don't deport you if you're leaving anyway. If you've overstayed your visa, they can however stop you from returning for a certain period of time. This is rare however I have seen it happen. You say your work permit is "underprocess" - do you have a
promesa? If so, you should keep it with your passport.
2. Before EU entry when I needed a work permit there didn't used to be a problem, though I was given a bit of paper called a
promesa. This may have changed, and may vary by country of origin.
3. No. You don't need a letter or approval in order to leave. Returning to Schengen though may be a serious problem if your visit visa has been overstayed.
A good place for advice would be a Russian language forum like VK. There will be plenty of people from Ukraine (who until very recently needed visas etc) and perhaps some people from Belarus who are in the same situation. In my own experience, it's rarely a problem leaving Poland, however the important thing for you is if there will be a problem returning - the best thing you can do is to speak to people from Belarus who are doing this now or people from Ukraine who have done this recently.
