My wife and I have been married for a year now she legally came in to the US with a K1 visa but we haven't applied for AOS because the agency we're going through has told us that we shouldn't submit our paperwork just yet that there is a possibility that our application will be rejected because of my income. Is my wife illegally in the country because we haven't applied for AOS? and If we summit now are we going to get rejected because we took too long?
