I know of a PT from the Phils who arrived early this year on H1b but is now having problems because his petitioner just withdrew his petition recently. He claims that the withdrawal was for some reason unknown to him. Give him the benefit of doubt but the employer can easily do that for any reason. I believe PTs and nurses fall in the same category of workers. So the process and coming over here may not pose any problems now, but people considering this route should also consider the months and years ahead.
