Here in the states, time on type is not so much a deciding factor. If you can get the right to live and work in the US, you can apply at any carrier that is hiring right now. With your times, Atlas (747-4/8) Virgin America (A320), jetBlue (a320, e190), SWA (737, but the most lucrative job in the States), and a few other 'boutique' cargo carriers would be a good options. Also there are a few charter 737 operators too. But once again. If you get hired its all seniority on what equipment you can hold. It doesn'tt matter if you where a 737 fleet commander, you will fly the equipment you can hold!
Best wishes!
