I think this move will be pretty risky for non-US citizens/immigrants, considering the retrogression.
if one doesnt take the NLE, one cannot practice. yes, you can still take the NCLEX, but with the retrogression, assuming nothing will be done to solve it, then one is "stuck" in the phil for about 5 years with no training whatsoever. and thats an awfully long time to be stagnant.
if one takes the NLE, she risks getting into the hullaballoo of cheating and hopes to God the exam will be clean. assuming the exam goes on without a hitch, and that the retrogression is still on, one can expand his/her own horizon and look at other countries to work in, as these countries require a license.
if one had direct access to the US or its intended country of practice, by all means do not take the NLE. but if you think it will take a long time before you can leave (i wont tell you whether or not to take the exam), you should decide very, very carefully.
