you're on a work visa, not doing time in jail lol Of course you should date. It really does sound like you like to plan and control life, maybe a little too much? You really have to go with the flow in life.
I'm here for 3 years, in my 20's (ie., the prime of my life) and there's no way I'm not dating lol That's ridiculous. No relationship is ever serious in the beginning anyway, you have to get to know someone and that takes time. Just go out, meet people and have fun. If love happens, then you can figure it out. And easily.
If you want to move back home once your assignment is over, then I'm sure there are a lot of men who'd move for you. And who knows, you might really like living in the USA and staying for love wont be a huge comprise.
There are no guarantees in life, ever. You could be married and your spouse could announce one day its over. Not to sound pessimistic, but I'm just saying lol Stranger things have happened. You simply cannot plan and control everything.
So by all means, DATE! It sounds like you're outgoing and enjoy meeting people. You're in a foreign country, so get to know it. And that does comes through getting to know its native inhabitants
