Brother,
Very good post. I understand your feling since I also went through the same path for 10 years. I graduated in 2001 and sept 11 happened and problem started. After 2003 market started picking up and got a job and finally got my GC. I request  you to prepare what you know the best. if you can take certification on your particular field will help. Keep looking for job and even work for free couple hours a week if you find on  your own field. Mostly look @Dhoti company they may give you job for less pay. The good part is that you don't get more money there but you will be keep going with the life. Request them to file your GC and ask them to keep all money and pay you for living .. like say 50K or something... based on your experience and the location you live it may be up and down...

Find a way brother, you will see a bright horizon soon... Hope for the best. Post your e-mail so that someone will guide you to the best .............
