Thanks for the answer, I really appreciate, ofc it I need to look deeper in all of this but it seems good news so far. I have a friend in a regional feeder in USA, he told me more or less the same, to try to find a job with a quick upgrade or direct entry CPT in part 135 and after some time, try to join a major.
My wife and I spoke today with a layer, it would give me a multiple (for entry and exit of USA) visa for a duration of 5 years initially and can be renewed unlimited depending of my wife situation + a work permit valid and to renew every 2 years.
Not the most important but I already have some USA and Canada experience as my European airline was doing wet lease in Canada the winter, so I operated the 737 as CPT in North America for little bit of time.
