you can have a company, but without the Thai employees paying taxes and social security you can’t get a work permit or visa off it. I also have a company but I’m on a non o Thai spouse visa. That might work for you.
That happened to me back in September. I booked a hotel and then the next day I got an email from Expedia explaining to me that the hotel has been closed and my money was returned. And I also received a 20% off coupon.
I brought my sons ashes back to Thailand and the funeral home did the paperwork for me. Also make sure the marker, a small metal coin like thing is in the urn. That has a number on it that will match the number on the documents. Hand carry the urn and notify them when you check in and at security. Coming into Thailand they didn’t check anything.
