what "forms"? if you filled-up & sent a paper form to an "address in the US", then that's a scam. applicants for this visa program can only apply on-line. however there are 3rd party brokers who does the application for y ou for a fee... & this is where scams takes place in some cases.

if you need to know more about your status, go to www.dvlottery.state.gov which is the US' state department official website.

hope this helps!
