Not true.
My checks were cashed last week . I got my receipt nos from back of the check. I am able to check using that. The only thing they do to update the system is although your checks are cashed days ago,it appears maybe after 4-5 days in your online bank statement. In that way they can update the system for our use.I havent got any receipt as such or fingerprint notice. I can still check using the receipt no behind checks.
I am afraid that all you can do is wait...
1. If the checks were cashed then it means your receipt is on its way.
2. Online information normally (as in my case also) does not appear until you have done your fingerprints, and in your case you have to wait for both notices.
3. If you call USCIS then they will ask you for your receipt number(which you do not have) and then they will tell you to wait(maybe 90 days before calling again)
*stinks right*
But your case may be different, you never know.
