Hi.
Anybody familiar with the new fee 165 dollars os155a green cars policy. I have paid the fees before they came here. 2 weeks after they came here. I received a 797 notice stated that " fee in suspense" about their cases. How long does it take for them to verify that they actually get the payment and continue processing the green card application. I went online to check the status using the receipt number. It says that they have requested a waiver for the fee. Which they never did. Was that is a mistake ? Anybody recently gotten his or her green card with this new 165 fee? Please share the same experience. I called the 1800 number of uscis and was told that I need to send proof of payment to the processing center to continue the process. How did they miss the payment if it's already clear from my checking acct long time ago.
Thanks for any advice.
