Several land borders require 2 nights out of the country, a flight ticket and proof of funds for a 60 day visa exempt entry. How does immigration approach people like OP that is married and do this entry with the purpose of restarting the process, to convert the entry to a NON-O based on marriage and 12 month extension at a local immigration office?
I have had the same experience. Even though the bills were in perfect condition, the lady scrutinized the bills as if it was forensic science. It took her a minute of relentless search to find an invisible spot at the edge of the bill and refused to accept it. We had a heated argument until she accepted the equivalent amount in Baht.
Correct me if I'm wrong. Unless you will apply for a Multi-Entry Non-Immigrant O, the embassy in Vientiane doesn't list any financial requirement for a Single-Entry Non-Immigrant O (Family member of a Thai national). As an option to Savannakhet?
