Yea i did thats why they send me RFE...

I send my italian driving license and my internation license, also proves from the day i left and when i came back...also i wrote little letter thankin them and stuff..

Btw everyone beside here told me not to waste money applyin for i821d cause i was out of the country for 6months, even a lawyer that i talk to told me not to waste my money but guess what, i did all the applications my self and got approved!! So everyone keep ur head up and dont let people put u down..
