Hey I'm illegal, and trust me it's not by choice.
I got all my second bachelor in USA with all my pilot licences "made in USA". Alas, to obtain a work visa you need to justify that the job requires a bachelor. Pilot is not recognized as a "high skilled job" and does not require a bachelor, thus no way for me to get my papers. (Even if airlines require a bachelor for their pilots).
I'm working for a construction company, I cannot get my papers either because it is not my "education", I didn't go to school for it and justify "special skills".
So I'm stuck, I had to use the backdoor and get marrired to a girl that is making my life a nightmare and I will have to divorce anyway probably loosing my possessions and still have no paper.
Oh ... and I'm paying my taxes, and my car insurance and all the stuff that a citizen have to do.
I tried everything, for his election Bush said "less green cards/work permit for foreigners". Now he's doing a 180 degree turn (Maybe to win states like California/Florida). Whatever, for me it will be an opportunity to be leagal, and afterall for INS to know where I am, what I'm doing.
About homeland security, when the thing will calm down I can tell you some stuning stories that really make you wonder. I see a lot of tight measures taken, and I see them in action everyday, but in the other hand I see wide open cracks that I don't even have to look for.
