I guess this goes to the "Anything Else" category. I am currently working getting the I-130 done for my wife (prerequisite for the CR1) and needed some Thai translation done. I reached out to [members only]/ and they did a fantastic job! Not the cheapest option, but rapid turnaround of one day and ticked all the boxes for meeting USCIS requirements. If you are looking for translation services on the US side of things, I have found them to be perfect. <disclaimer I am not compensated for this in any way>
