Chicago Illinois! I have my bio appointment 9/28

Well if anyone saw my other post, I was terrifite of getting a cut on my fingers. Well about 14 hours I will have to take my pic and finger prints. I'm not sure what to bring but hs ID and my matricula.
Any tips or anything I should be ready for? I'm excited but also scared in the same time. I'm kinda happy to get this over with but then it's time to wait and see when I get aprove. My case is simple clean and relevent. Graduated last year from hs..so I have no evidence missing. Well I'm just going off on this post but I can't sleep.. I've waited for my appointment and did not do a walk in. Let's see how long it takes guys, even tho I've herd texas location is taking for ever to approve people.

If any tips or what to bring let me know. Thanks

Don't be afraid.

Which ASC are you doing your biometrics?

Don't worry. I went in for my appointment today (9/27)at 8am, and it took about 10 minutes.

What ID did they take? And I'm going to the one at chicago

I'm going to the one in Chicago down town. But what I'd well they take?

There's ASC location in Chicago. One in the Southside and one in the Northside. You don't have a valid passport?

I do not. Well that be a problem? Hs or Mexican matricula won't do the job

I guess bring both. Does your matricula has your signature?

Yes it does. And well that be a problem? And if any questions...how should I respond. Like status and all that.
