Hey everyone,
I received my LTR visa without any problems. It took the BOI around 3 weeks to see thru my documents and sending my the endorsement letter. After I submitted the endorsement letter to the Thai embassy of my home country it took another 4 days till I had the LTR Visa in my hands. it could have been faster if I had a certified translation of my taxi come return right away.
It was a very fast and easy process. If you check all the requirements the LTR visa is easy to get.
Wish you guys all the best!
