J1 hours
My first job was in Boston where I flew very little in winter time.... I moved to Florida and flew 80-110 hrs a month. If you are a CFII it really helps to get more hours than an regular CFI... you have also more chances to build cross country and night time which is a plus too.
Personally I don't know any J1 guy who built less than a 1000 hrs... usually they are motivated and quick students and have about 18month left on their visa when they start working.
PM me if you have any specific questions!
cheers
