We have answers to the most popular questions from our customers. If you can't find an answer to your question, please contact us.

What happens if USCIS rejects my application?

When USCIS rejects your application, it means that you filled something incorrectly. Rather than reviewing your entire case to see if you qualify for the benefit you applied for, USCIS sends your application back to you and does not cash your filing fee check.

Can USCIS deny a waiver?

We will deny your underlying application or petition if we determine that it involves false documentation, misrepresentation of facts, or other fraud, including fraud on a fee waiver request.

What is the N-648 form for?

N-648, Medical Certification for Disability Exceptions. Use this form if you are applying for U.S. citizenship and need to request an exception to the English and civics testing requirements for naturalization because of physical or developmental disability or mental impairment.

What happens if a fee waiver is rejected by USCIS?

There is no appeal of a rejection of a fee waiver request. Requestors may, however, file another fee waiver request with the required documentation to establish eligibility. An applicant may also refile the benefit request with the proper fees for USCIS to process the request.

How much does N-648 cost?

N-648 Frequently Asked Questions On this office visit, you will make a non-refundable payment of $300.00 to schedule the Initial Interview appointment with the Psychologist. You will pay the other $300.00 when the Psychologist determines you meet the criteria to proceed with the Psychological Testing.

How will the USCIS interviewer approve or deny an N-648 disability waiver?

An immigration officer may deny an N-648 for insufficiency, lack of credibility, fraud, or material misrepresentation. If your N-648 is denied simply for being insufficient, the immigration officer will proceed with your interview as if you had not submitted an N-648 (testing you on English, civics, and so forth).

What happens if USCIS rejects an N-648 disability waiver request?

If the N-648 waiver is denied at the naturalization interview, USCIS will proceed with the interview as if you had not submitted a Form N-648. USCIS will provide you with an opportunity to take all portions of the English and civics requirements.
