I have a question, my friend is Russian and is here on 30 days exemption stamp, he says that he is not allowed to get 30 days extension on it because of his nationality. Is that correct?
TLDR : Answer Summary
A Russian citizen on a 30-day visa exemption stamp cannot extend their stay beyond the initial 30 days. This is due to restrictions placed on nationals from certain countries, including Russia, which prohibits them from receiving the standard 30-day extension. Instead, they can apply for a 7-day extension for a fee, but must leave Thailand shortly thereafter.
