Savannakhet vs Chicago

[ubonrthai]

I'm planning to change visas and apply for a non-O based on visiting my Thai spouse. I could get it over with in Savannakhet soon or do it in a couple months in Chicago. It looks like Savannakhet could give 1 year-multiple entry and Chicago only 90 days-single entry to start. I'm thinking I should just get it over with in Savannakhet since I'll be in Mukdahan soon anyway. I saw the recently reported required documents. We were married in America so will it be the original คร.22 we received in Chiang Mai many years ago that they want to see or will they want the U.S. original marriage certificate? Also, how soon after returning to Thailand will they want to do the home inspection or will that only happen the following year when I extend in-country? Thank you.
