renounce citizenship of your country of birth ..before the gc interview off course
some guy from ecuador that I was working with did that and got to stay in the usa
went to interview with the lawyer ..some legal wrangling etc but he got it at the end ..remember you have to o it asap before your other documents expire.;get the DL from the state you live also before do that
good luck
ps this so called experts on the forum would never give you straight advice ..street wise advice that is ..
