My Thai divorce certificate’s english translation simply has a stamp saying it is a certified translation by the ymca, which was listed by the embassy as an acceptable agency to do certifed translations.
No other statement or attestation that it is a accurate translation, simply the certified translation stamp.
So I agree with your company, that is all is needed and you are reading too much from the internet. Surely, they have had countless experience and would know if it is not adequate.
I have used my stamped certified translation with uscis and different embassies without any issues.. a scanned photocopy nonetheless. never did they even need the originals. this goes for uscis, usa embassy in Indonesia, Philippines, ..
