Be prepared to spend from 15,000 to 20,000 Baht for fees... and another 15,000 to 20,000 in miscellaneous fees, travel/hotel costs and other ... Maybe you will be lucky and it will be 50 or 60 percent less.
The Agent needs to be in your area. You need an accountant to prepare certain tax statements and more working with the Agent. Accountants are often Visa agents too. You have to have an application into the Labor Ministry - either a WP.1 or WP.3 depending on several factors ... Only an Agent will know which you need. Your Thai Partner will have to prepare a letter inviting you to be employed as a Director ... Getting all this done in the right sequence with the correct documents only an experienced Accountant/Lawyer/Visa Agent will know in your particular case.
It is entirely plausible that the inability or unwillingness of the employer to provide info about items 10 and 11 is that the employer is not in compliance with payments or numbers of Thai employees reported or both.
I read that Tod but to me it was not clear in the phraseology used - just trying to clarify "to be" means in the future - and both could be in the future
Jim the M in the O-A visa stands for Multi Entry. As far as I know the O-A is the only visa type with dual properties. In the first year a person on an O-A visa could choose to just do Exits and Reentries every 90 days instead of Reporting to immigration. Or choose to do 90 day Reports. But must do one or the other. I am not sure what happens when the actions are mixed. The Non Imm O and Non Imm B Multi-Entry Visas only have one choice - Exit and Reenter every 90 days. One Year Extensions of Stay (extended from Non Immigrant Visas) make 90 day Reports.
