It's tough if you have low hours. There is a lot of competition here. Corporate is tough to...BUT...the one ace up the sleeve is the ol' "who you know". I know 250 hour cessna pilots get a gig flying Gulfstreams because of who they know. If I were you, I'd use any other skills I have and get in the aviation biz in the US. That could be in the office of a corperate operation, airport management, anywhere where you have exposure to the operators. Treat them well and you'd be surprised about the doors that open up for you. Do you speak multiple languages? obviously you do, so everage that. Swallow your pride and teach on the side. You just might meet some rich guy who has a Citation and needs a pilot.
Think outside the box. Leverage your skills for a job close to the action. Shake hands and expand your network. You never know, you might find a non-flying job you love too.
