My experience
Received Letter 7-03 case with adjudicator, enquiry revealed name check-- completed august 2004. Case according to visit to Vermont with Adjuducator
since 8-30 no news, H1b extension instead got renewed,
Congressperson confirmed but could not give deadline this time.
Derivative case was told after case enquiryin mAy 04 case with adjudicator
and hear in 30-60 days No reply nothing.
In summary if works out that is okay otherwise some chec is pending!
