Khayat, the biometrics notice is still being expected, when I called USCIS, I was told to expect it before my interview date, when I probed further by asking that what happens if it does not get to me before the interview date, then the officer said, it will be done on the same day with the interview. I still have two weeks before the interview so the notice should get here before then, however, I will go to the field office to talk with them. The earliest day is next week for infopass, I will attempt to get audience before then.
The interview letter has a 1st page which is the normal typical form I-797C, that has a list of items, the applicant is to bring only the items that are checked off. The 2nd page is an ordinary white sheet of paper titled “appointment checklist” that contains the following: (this might differ based on field office or applicant)
• Passport
• Original birth certificate
• Marriage certificate
• Copy of payment receipt to DOS
• I-94 record - Proof of lawful immigration status
• Proof of educational or work qualifications
• Driver's license
• Originals of all documents submitted with the application
My thinking is that they are generic items/documents being requested, to be safe it’s better to go with originals of all related documents. In my case these are documents that I have submitted with my application so I will merely take the originals and one photocopy of each with me. They did not indicate that i should bring affidavit of support etc but i will go with some financial documents such as bank statements, pay stubs, employment letter, etc, but will not present them unless requested.
