Are you on non b visa (90 day sticker) or extension of stay. If the former then you and your employer only need to deal with Labour Department and you can enjoy the rest of your non b visa and leave at the end of it.
It's very common for Thai people to live in provinces other than where the it TB is registered.
Al your wife needs to provide is copies of her I'd card(front and back) and copies of her TB. Al signed as true copies by her.
Depending on your immigration office, you wil need copy of lease, copy of landlords I'd (front and back) copy of landlords TB, copy of landlords TB of the property he's renting out. All signed. If your landlord is a foreigner, then copy of his/her wp (Good luck with that). Not the same for all IO's. Check with your local one.
sure! I was just wondering why they would want it as its not connected to the extension unless using the incom within Thailand method. I never mentioned my WP and they never asked. No worries.
May I ask, without wishing to hyjack the post, how is your wp linked to your non o (married to Thai wife). Did you use income earned in Thailand previously?
