I was AOS-interviewed (family-based) in Houston INS on Dec, 2002, was told to get approval letter within 2-3 months. But almost 6 months went by since then, and I get no further response. I got up as early as 4:00am to line up for status check in front of INS gate last week, and was told by a officer that they need wait for my security clearance result. What should I do? Anybody is in same boat in Houston? How long does security clearance take generally? Can I check if my 'security clearance' is clear or not? Please help me. My God! 6 months!!
