used my two sons names without any problem...

Maestro: thnx for clarifying...

Since you are married to a Thai you can get a work permit and work with a non-o visa or an extension of stay based upon marriage.

You should get a non-o visa before making your trip. If you can qualify for an extension by showing 400k baht or 40k baht income you should just get a single entry and apply for the extension. If not then a multiple entry non-o would be best.

Presumably, to show 40k baht income, you will need a work permit or is it acceptable, if the income is shown outside of thailand?
