thanks for the reply. So, you think from the letter that they only need some school records with the date of birth and that will be sufficient?

For the K1 interview we provided the "Letter of Affirmation" and it was OK for that

My wife is from Thailand. She arrived with K1, we got married and we have submitted the I-485. She never had her original birth certificate. Her parents lost it. When filing the I-485 we included a copy of a "Letter of Birth Affirmation" from her local registry office in Thailand and a certified translation. This "Latter of Affirmation" has her date of birth, ID number, address, name of parents and their DOB and ID numbers, and witnesses present. 

We received a Request for Initial Evidence from the USCIS about 1 month after filing, asking us to submit secondary eveidence if the birth certificate is not available AND a letter from the government or other authority. 

Can anyone help me figure out what additional evidence they need? 

After getting married, and awaiting green card, is it possible to travel outside of the USA?

We have a problem. The Dubai police require a copy of the visa from my fiance's passport. Unfortunately she no longer has the passport from 10 years ago!

Any advice?

My fiance is from Thailand. She worked in Dubai for about two years. That was about 10 years ago. What is the likliehood that the US Embassy in Thailand will ask for a police clearance certificate at the interview if her time in dubai was that long ago?
