It's a fine idea but you don't need a year. Take a one month leave of absence from your job which I'm sure will be rapturously granted once you explain the purpose. Prepare the ground by asking family and friends in your old country to look for suitable girls, to whom you would be introduced ahead of time. Once you're there you should be able to narrow down your focus to a few candidates within the first two weeks, and make your choice by the end of the month. Then you invite her to visit you in the US to seal the deal.

A month should be plenty of time if you plan ahead -- and if you still fail to find a suitable candidate after a month, it is likely that you would fare no better in a year. Might as well make the whole process as efficient as possible and keep your career on track.
