My bank manager says differently. I very much doubta lowly branch manager at either of our banks has the inside track of what is happening. The branch managers at BB had no warning of HQ decisions.
Get a METV. That can get you almost 9 months in country with good timing. Easy to switch to a B for business if you set up Ltd company etc EDIT: Just noticed you mentioned language classe3s - an Ed would do too.
1) yes 2) Fine you will have no issues. That is what the visa is designed for 3) in theory CC Cards spending is included in remittance according to a few tax advisors. In practice I have more chance of dating Margot Robbie.
As others have suggested contact the Embassy. It is known to be a stickler for the rules but it is also very efficient. If all docs are aligned they process quickly. Good luck
Great you got it done. I think your agent got around the "Rules" though rather than being changed but so what if it worked. It is usually a long term residency or with a 1 year WP or a Thai returning home. Does not matter though if it worked for you.
They are generally 90 days for eVisa and 30 for older types. The poster says they arrived 18th and only had a visa till 25th. How is that possible? :-)
