I suspect to secure employment post 911 with a part 121 carrier that you'll need full citizenship as demonstrated by actually holding a US passport. Not specifically the letter of the law but it's the way things currently are. Expect no feedback from the dregs of HR when you fail to be hired.
There have recently been a few sensible and very necessary amendments to the required flight experience for securing employment as an airline pilot. This puts the RHS in anything of worth with logbook hours totaling 200 even further out of reach.
Interested in Europe? Well then, direct your post to Beelzebub and he'll spin on his axis and mendaciously explain how 200hrs makes you a king of the skies - zero to hero and all that sort of thing. You'll be a mentored, pampered and monitored product from a pilot factory who after beating the herd will graduate with a cheesy grin and no worries. Do please however note that you'll have to pay a considerable sum for admittance to the club - and the passport thing will still be a problem. Plus the product is more than a little suspect.
Sorry eightyeight - no easy answers. You (like most of us once did) need to build time. The hard truth is that there's little possibility of you finding employment in the US of A so best you cross the possibility from your list.
I sincerely wish you all the best with your endeavors.
