Old timer with newbie question. Just sanity checking if any rules changed recently. My Non-imm-O visa based on spousal support (marriage) is up for extension (application prior to 1 month consideration) on August 17th which is this Saturday. Prefer not to leave it until Friday, so is going a couple days in advance ok or will they say come back later? This is in Chiang Mai. Thanks in advance for any words of wisdom.
