I filed for I-485 and I-765 on April 15th to Chicago lockbox. Package was received by USCIS by Apr 18th. USCIS attempted to take payment from my credit card on April 29th, however Capital One declined the payment as they thought it may have been fraudulent. Since then I have not received any further information, nor had my package returned. Have inquired with 'Ask Emma' on the current status of my application, however the USCIS agent was unable to find my file on their system, so advised I should email Lockbox Support. It may take between 15-30 days for me to receive a response.
Frustratingly, the entire process is beyond cumbersome and full of various pitfalls! USCIS are beyond inefficient.
