moving to america

[jaffag]

my dad applied for me to get my 1-130 immigrant petition for relative visa in 2004,he was then a legal citizen,2 years ago he became an american citizen,so i got transferred to a different waiting list.my case is still pending,all checks have been passed,does anyone know how long roughly visa's take to process?the website isnt much help,and when we rang we gave up waiting after 4 hours on hold,thanks
