US Visa Declined again...

I was told nothing has changed since my last application.
Even though I had proof of a job after my training that would take me outside the USA.
I was given the reasons: I might fail my training or Helimission might go bust. So I couldn't argue with that kind of reasoning.
We now have to apply for the green card which is permanent residence.
We don't have a time scale on how long that takes so we are taking it one step at a time.
