I have 3 years validity in my passport, if I apply for the dtv visa now( 5 years validity), would there be any problems when I renew my passport later.
TLDR : Answer Summary
When applying for a DTV visa with only 3 years left on your passport, there are important considerations. It's essential that your passport has at least 6 months of validity for the DTV application to be approved. Once you receive the DTV visa, you must retain your old passport, as it contains the original visa details. If you renew your passport while in Thailand, ask your embassy to return your old passport, as you’ll need to present both the old and new passports when extending your stay or re-entering Thailand to ensure the immigration officials correctly link the DTV visa to your new passport.
