My wife’s h4 got expired on Mar 21, 2013 and we haven’t filed her H4 extension and she left the country for stamping and they gave 221g asking for her dependent I-797, but we don’t have it as we did not file her extension as we didn’t have much immigration knowledge. She stayed on "unlawful status for almost 10 months. Please suggest what needs to be done and suggest as I’m not able to figure out this solution?
