as for friendly my experience has been that the immigration officers are extremely friendly and really want to help you. But you have to follow the rules and let them check all their boxes. And the more boxes, the better in my opinion.
Having to run around town to get marriage registrations updated, and get detailed information on the house you own or that you rent, plus pictures, plus the in-home visit by the immigration officer... all helping to keep Thailand the best place in the world. I love it
no i like it difficult and cumbersome... keeps the riff-raff out. Already cutting the visa exemption down to 30 days. I'm ready for them to get rid of that DTV visa next. Love it
depends on what you mean by "hard". Lots of paperwork. Lots. You'll take trips to various places. They will probably come to your house and take photographs of you and your wife. But certainly doable if you are motivated to stay in the kingdom on a yearly extension and want to be eligible for a work permit.
