really, the starting career options in the states now are very good.
there are many regionals that are hiring, and the minimums are getting very low, similar to that of before 9-11.
flight instructors are also in demand as people are quickly moving to the regionals.
the short term outlook for the majors is poor. the retirements should really open things up in a few years, but the u.s. airlines are in bad shape, and it isn't getting better. even the once rosey outlook for the discount carriers is becomming a tad tarnised.
the problem you face is your status. airlines are now very resistant to hire non-green card holders since the requirements and work that must be done concerning the work status. green card holders only seem to have minor problems with this.
also, you need to send and re-send applications. call the human resources department and find out what they are looking for. so call, and send, and re-send, and call.... most regionals like this - they want to see ambition. a few don't. skywest some years ago used to be of the opinion 'we will call you'.
