K1 Dallas Lockbox address confusion

[henny123 0]

Hi everyone, I am confused of which address my bf ( the petitioner ) can send our k1 visa application. On the website it says :

For US postal Service:

USCIS

P.O Box 660151

Dallas, TX 75266

For express mail and courier deliveries :

USCIS

Atn-I-129F

2501 south state highway 121

Business

Suite 400

Lewisville TX 75067

--so my bf is residing in Massachusetts , and we chose the Lewisville TX, is that okay? Or is this when the petitioner is sending it from outside the US?

Please help, I want to make sure everything is right with our application

It depends on how you are sending it.

The first address is a P.O Box, so it's just if you send it USPS and the second one is for Fedex, UPS, etc.

Yea, it depends on how the petition package is mailed. If mailing regular (certified/delivery confirmation) mail through post office send to first address. The second is for Express Mail through Post office or Fedex, UPS and such.
