Basically the law is, you can't legally do a job a Thai person can do... Meaning you can't legally take a Thai persons job. That being said many come here and start companies, which is a bit complicated and in the end you own at most 49% of the company.
That my friend is a matter of opinion. This group thinks... but it really doesn't matter. What does matter is what the Embassy thinks, and I am honest with them.
I would discourage the marriage visa. It's a real pain in the neck. I have talked to a few fellows who have a Thai wife but meet other visa requirements and they prefer go with the other option over the marriage visa option. I talked to a couple of agents and they wanted $$ to do a retirement visa but $$$$ for a marriage visa.
I have been doing visa runs for several years now. You can do it that way if you want, but there are some risks involved so maybe not the best option (still better than the married visa option).
Almost certainly you will have to replace it. It looks like maybe it's a US passport? I recently replaced mine, it had taken about 3 weeks.
Once you get the replacement you will need to transfer stamps, which requires a trip to the local immigration.
I would be curious if you could just exit the country with your busted passport. I recent traveled on my new passport, I gave them both passports on my way out, they did a sort stamp transfer at the airport. It adds 20 minutes to your time to get to the gate.
I *think* you can get emergency travel documents. I *think* those are only good for going home.
You do not need an agent to do a visa run. You benefit from an agent because they have the transportation planned out. You simple get in the van and play follow the leader. Otherwise a person has to figure out all that stuff for themselves. Not hard but easier not to.
Agents often know which immigration officer to go to, or avoid, which is another benefit.
My agent takes me to the Cambodia border and brings me back 4500. If I wanted to do it myself it would cost considerably more and take longer.
As silly as it sounds.. If you are the president/CEO of your LLC, you may be able to write a policy letter, ALL EMPLOYEES ARE REMOTE, then throw in some details for good measure. Work should be completed between the hours of.... We do not supply... Its the employee's responsibility to..
