Depends on how serious you are about where you want to ski.
If you want to live/work at a mountain and have the flexibility, avoid the East Coast - You have traveled a long way and might as well take advantage of what we have here in the US.
I would say move and work at a marquee mountain for the experience: Jackson, Squaw, Snowbird/Alta.
Moving up to Bozeman, MT and working at Bridger would also be fun.
If you just want to ski park and party, yea go to Colorado.
If you just want to party, stay in NYC.
I lived in NYC and now live out West. Skied a lot at Jay, Killington, Mt. Snow, Stratton, Hunter, Magic, Sunday River, ETC.
Go west young man.
