I am not trying to hide anything in my background. I am just interested for figuring out how long it will take to check my background. I have lived in the America for the past 11 years (6 of which have been as a citizen). And before that I lived in Germany. I moved here when I was 24. Do they check back only 10 years? If not, I think I am out of luck because if they have to go to Germany to invetigate then it will take a very long time and I am 35 right now. I dont have long!
