This is an interesting program and could be successful, if done correctly. A wide pool to recruit from, experience in a ‘team’ environment and exposure to structured training and strict adherence to workplace rules.
Although the above pros are overly simplistic, there are no doubt some negatives that will arise as the program matures - interesting times.
Noting the time taken for this to have an impact, I think the next chapter will be 135 operators seeking E3/H1B visas.
