Is it advisable to renew a passport before applying for the DTV visa if there are three years left until expiration?

The discussion revolves around whether it is better for an expat in Thailand to renew their passport, which has three years before expiration, before applying for the Digital Tourist Visa (DTV). Many comments suggest that renewing the passport might help avoid complications with visa transfers, particularly since some users reported challenges when trying to link a new passport with a DTV that was set in an old passport. It's emphasized that the DTV is primarily a document and not a visa stamped in the passport. Several users recommend getting a new passport for greater peace of mind, especially considering airlines typically require at least six months of validity remaining on a passport for international travel. However, others argue that it is not essential to renew the passport just for the sake of the DTV, as users have had success entering Thailand with both new and old passports as needed.
