urgent question about approval letter

[John Smith 1]

as you know guys i received email from ins aug 18 stating my case is approved,

today i received approval letter, there is something strange about this letter,

i cant understand,the letter says" prior to to receiving permanent card you

may be required to report for BIO PROCESSING",

i already did my bio on aug 2,

my question is do i have to do another bio?
did the ins receive my bio i did on aug 2 or no ?

i would be grateful to you guys if you explain to me what is going on ?

sorry , one last question when will i get my GC?

don't worry it states "MAY BE REQUIRED" and if you did the BIO probably it will not be required. After I got approved I setup an appointment and did the bio without them asking ...a month later the send me request for bio I called and the rep said disregard the request (actually it states in the request "if your case was approved ...ignore this notice" ) Congrats
