HI, I DON'T HAVE MUCH EVIDENCE TO PROVE THAT I WAS HERE BETWEEN 2007-2012 SINCE I GRADUATED HS IN 2005. NEVER GOT A JOB OR DID THINGS THAT WOULD LEAVE ME WITH DOCUMENTS. I RECENTLY CAME ACROSS MY DADS INCOME TAX RETURN FOR 2007 AND HE LISTED ME AS A DEPENDENT. IT SHOWS MY NAME , SOCIAL NUMBER, AND HOUSE ADDRESS. IS THIS SUFFICIENT ENOUGH TO PROVE THAT I WAS HERE IN THE STATES FOR THE YEAR 2007? ANY ADVICE IS MUCH APPRECIATED, THANK YOU ALL.
