No problem with that. Keep the jobs for Thais. Maybe if our home countries did the same we wouldn't be in the shit we are. Anyway probably OK if we work on something we own.
Don't know if it helps but in the small town in Thalland where I live there are two black American guys. Both married to Thai women and no problems. Accepted by everyone as far as I know.
shouldn't make any difference. My bank account (Bangkok Bank) was originally set up in Udon Thani when I was living there. Now live in Nong Khai and the Bank there now supplies all my info for immigration. I have changed my address with the bank. So even though my account is still with Udon bank, they have my Nong Khai address.
In theory it should replace the need for a certificate of residence from immigration. But as this is Thailand, sometimes it will then sometimes it won't.
