1. How long it may take to prepare I-485 and how much is the cost for retaining the preparation service?
In general we take around 7-10 working days to complete I-485, and our fee is $1000 for the principal applicant and $500 for each dependent.
Write the applicant's name with a pencil.
Please do paper clips or nothing.
4. As a supporting document, do I need to submit all pages of our passports or just the bio pages and visas?
No need to submit all the pages, the bio pages including personal data and emergency contact page as well as visas will be fine. Moreover, please do not forget to submit all the old and new copies of passports for both the principal and derivatives.
5. I was not sure if the I-485 application contract (retainer) covers RFF’s as part of the attorney fee. Can you clarify if I get an RFE, will the current attorney fee cover responses to RFE, or do I have to provide an additional fee for that?
Yes, the contract (retainer) covers RFE as well. No need to provide an additional fee for that separately.
6. My mother's signature on her passport is in Bengali. Should she give a Bengali signature on the notarized document in support of the DOB? Or should the signature be in English in this document?
The signature of the Affidavit of Birth does not have to be the same as in the passport. She will be able to sign as she wishes in both Bengali and English.
