Crossing the Hungarian borders is restricted from 1 September to most foreign nationals. The good news is that you can get an entry if you visit Budapest because of your real estate business.Based on Government Regulation 408/2020. (VIII. 30.) if your travel has business or economic purposes and you can certify it upon entry, you can proceed without restriction. You need to receive an invitation letter or certificate from the Hungarian firm you are in contact with. It must be an original document printed, stamped, and with official firm signature – it has to be via postal mail.The certificate must be shown to the officials at the border control upon entry. You can expect a temperature check, but quarantine is not mandatory in this case. In case the officials experience the typical signs of coronavirus on you, your entry will be rejected.
