i came to the united states when i was a kid thru a visitors visa and overstayed . i got my married to my wife 2 weeks ago and im trying to fill out the applications. is going pretty good until i saw the biometrical ( background check) that me and my wife have to do. they are asking me for my working history. i have a tax id and i did my taxes for the first time last year because it was the first time i worked (didnt use other people identity. just a random number). also uin the paper that i have to fill to see if my wife has the necessary income to support me and be my sponsor it ask if there is another income ( that i have). should i put anything or leave it blank?
