I sent my OPT Extension application by USPS Express mail to the wrong address??

I sent my application to :

Attn: AOS
2501 S. State Hwy. 121 Business
Suite 400
Lewisville, TX 75067

instead of :

PO Box 660867
Dallas, TX 75266


You might be OK since that is the physical address to use when sending by courier (like Fedex). Has your filing fee check been cashed yet? If yes, you are fine. If not and your filing deadline is near, you might want to call USCIS and/or seek assistance from your DSO.

@SoTired I did same mistaken as yours… May I know how did you solve the issue after.??
