, Taking loads of extra documents is unlikely to help at all. In fact it can muddy the waters. :/
Usually you just show the two marriage certificates (if you were married in thailand) or the marriage certificate from the country you were married in, the thai wife's i/d card & her house book listing.
Something is not quite right about this :/ because it doesn't matter if it's the first time or the fifth time you've applied for that visa in Savannakhet, they routinely issue year-long, multi-entry NOn-O's based on marriage.. You don't have to go with him either..
