I went out of Thailand to make a passport and at work I was given just a week leave. So now my new passport isn't out yet, and my flight is due for tomorrow.
So my concern is if I get back to Thailand with my visa still valid for over a month and my passport for 6 months, will I have any problems with the immigration at the airport? I got a re- entry permit before exiting Thailand.
TLDR : Answer Summary
The user is concerned about re-entering Thailand with a valid visa while their passport is under renewal. They have a re-entry permit and a passport that has been applied for but not yet received. Many comments suggest that once a new passport application is made, the old passport is typically rendered invalid for travel, thus causing potential issues at immigration.
