My kid started a university program in Hungary in fall of 2015. There were some issues with paperwork regarding his student visa and he was issued a temporary visa so that he could finish the term and exit the EU.
When he exited his passport was NOT stamped leaving the EU or upon reentering the US. However the only entry stamp was from last August.
The issue is his student visa can only be mailed to his Hungarian address, so he's not going to have it until he returns to Hungary.
Any thoughts on the possibility of him being caught on entering the EU?
What entry points would minimize this issue?
