What i have to do after interview?

If you answered 32 out of 33 questions correctly, you are likely to be approved unless there are other factors in your case which concern the immigration examiner. In most interviews in which people miss questions, an examiner will give the couple an opportunity to explain why the question(s) was missed. But 32 out of 33 appears to be very good nevertheless. At this time, you may wish to either send a communication to the officer requesting the status of your case or make an infopass appointment to further discuss the status of your case with an immigration officer.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.

Hello. If this was the 1st interview, they may schedule another. I would recommend that you do an Infopass every month to check the status. Keep the Infopasses to show that you followed-up. They may also send a Notice of Intent to Deny if they question the relationship. Some offices have also send independent third parties to the house to walk around and see if it appears that you are living together.
