HI EVERYONE

i have question about the form DS-3032. what does CASE BARCODE STRIP mean?

THANKS

It's simply a method the consulate uses to track the paperwork. The barcode doesn't "mean" anything - it's tied to the individual's information and is generated when the applicant fills out paperwork using USCIS's online system.

Google Search: USCIS barcode

Previously, USCIS staff had to manually enter applicant data into the system. Now, applicant data passes seamlessly from the new Web applications into USCIS’ legacy system, saving significant time and allowing USCIS staff to focus on other mission-critical activities.

I think that bar code, if I remember correctly, means the case number, and visa category, and other info to track your case from their computer system.
So they just scan it to recollect the information from their computer system instead of typing all case numbers.
But who knows? It may be just cosmetic, and they may just type all case numbers in hand. :-)
