If you're all civilian with a bare 1,500 hours, you won't get anywhere EXCEPT a regional assuming you get the "right to work" here. The average off the street major hire has well over 5,000 hours, 1,000 jet PIC, a four-year degree and some "outside" stuff like check airman, chief pilot, volunteer work, etc. And many of those guys aren't getting called. It's still very competitive.
