Our last names are different. Also can you please explain what you meant by this?
but if you rush and tell there might be a souspicious fact. I cant imagine on what grounds they might think this case is suspicious? Can you please explain?
To flman95:
Thank you. I will remember that. "Dont tell, dont ask!"

and congratulation on getting your GC.
To cherr1980:
Yes, all my papers are correct (though we did not get married here in the US, we have our marriage certificate issued by the local authorities from my country). I have not been out of status, no criminal record, filed my taxes every year. Thanks for clarifying that not all states allow first cousin marriages, and i confirmed that the state we live in allows it
Once again thank you all for taking time to reply. I understand that you are trying to help based on what you think is correct (
and i really appreciate that), but it would be really really nice if anyone in the same situation who has been through the interivew let me know how it went. I can understand that some people dont wish to talk about it in a public forum, but can you pls atleast PM me and let me know?
Thank you so much and God bless you all
