My renewal timeline was UNDER A MONTH. I feel extremely lucky.

• My EAD was to expire this December.
• Filed within the 150-120 days.
• I filled and priority mailed my application with cover letter, usual copies, and signed documents.
• My receipt number started with IOE instead of the usual MSC.
• I live in the east coast and my application was processed through Nebraska
