OK, thank you very much for the additional information. Your answer is below.
Once you have received the information you need, please give me a positive rating of 4 or 5 stars. This is the only way I get credit for doing my job. I am sure you want to get credit for doing work, and I am no different. So this is very important for me. Thank you.
As to your first question about the police clearance certificate, you are not required to provide one of those for the adjustment of status process. If you were abroad filing for an immigrant visa or a fiance visa, then you would require one of those. But since you are in the US and doing adjustment of status, that is not required.
As to your second question about the birth certificate, it does need to have a certified translation to English attached. That can be done by a family member, friend, or a professional service. The certified translation format should the certifier's name, signature, address, and date of certification. Here is a suggested format:
"Certification by Translator
I [typed name], certify that I am fluent (conversant) in the English and [enter appropriate language] languages, and that the above/attached document is an accurate translation of the document attached entitled [enter the title of document].
I hope I have answered your question. My goal is always to provide you with an excellent customer service experience. I hope I have done that.
If I answered your questions and provided you with a positive customer service experience, please give me credit by giving me a positive rating. Without a positive rating, I do not get credit for helping you today, and I risk losing my job here. So I respectfully ***** ***** consideration of a positive rating, as this is very important to me.
And if you have any additional questions, you can still ask them even after you've given a positive rating.
A BONUS is also appreciated if you feel I've earned one today.
