Entered Thailand twice this year by land, without visa (had 30day stamp) New passport and entering Thailand by air 3rd time this year without tourist visa will be a problem??
TLDR : Answer Summary
The user questioned the implications of entering Thailand for the third time by air after previously entering twice by land without a visa. Community members clarified that while the new passport does not reset the two 30-day visa-exempt entries permitted per calendar year by land, entering by air may still allow for a visa-exempt entry, depending on the immigration officer's discretion. It was advised to be prepared with proof of onward travel and to consider obtaining a valid visa from a Thai consulate.
