I would like to travel from Budapest, Hungary to Lisbon, Portugal. I have a return (June 21 - 24, 2020) flight ticket from Budapest, Hungary to Lisbon, Portugal.
For the last 4 months, I was in Budapest, Hungary. I am a non-EU country citizen. I have a residence permit for studying purposes in Hungary. I could not find information about travel restrictions in Portugal and Hungary for non-EU citizens with (temporary) residence permits.
My question: What are travel restrictions when I will go to Lisbon, Portugal? Should I go to quarantine? What about when I come back to Budapest, Hungary?
