Well, let me tell ya, this A-number thing, it’s like a special number they give ya when ya come to this country, America. It’s important, ya know? Like when ya go to the doctor, they give ya a number, right? This A-number, it’s kinda like that, but for livin’ here.
Some folks call it an Alien Registration Number. Sounds fancy, huh? But it ain’t nothin’ to be scared of. It just means they got a file on ya, see? They know who ya are and where ya come from. It’s like, uh, they gotcha on their list, like when the school takes down the kids’ names.

Now, this F1 thing, that’s somethin’ different. That’s for the young folks, the ones comin’ here to study. My grandson, he came here on that F1 thing. He had to get that number too, the A-number. See, the F1, that’s like a ticket to get in, to go to school. But the A-number, that’s the number they give ya to keep track of ya while you’re here. It’s a long number, not short like the one on that F1 paper.
- F1 is for school.
- A-number is for everyone who stays a while.
My grandson, he showed me his papers. The F1 number, that’s the red one, easy to spot. But the A-number, that’s the longer one, like I said. It’s got more numbers in it. And ya know, that A-number, it stays with ya. Even if ya change yer school or somethin’, that number stays the same. It’s your number, see?
They say it’s seven to nine numbers long. That’s a lot of numbers, ain’t it? But it’s important. They use it to keep track of all yer papers, yer visa, yer work permit, all that stuff. It’s like they got a big file cabinet somewhere, and that number tells ’em where to find yer stuff. It’s like when I put my important papers in that old wooden box, I know where to find them.
The government, they call it the USCIS, they’re the ones who give out these numbers. They gotta keep track of everyone, ya know? Lots of folks comin’ and goin’, gotta make sure everyone’s accounted for. It’s like countin’ heads at the church potluck, gotta make sure everyone showed up.
So, if you’re comin’ here to stay a while, or to go to school, you’re gonna get this A-number. Don’t lose it! It’s important. It’s like yer social security number, ya gotta keep it safe. My daughter-in-law, she always tells me, “Ma, keep yer papers safe!” And she’s right. Gotta keep ’em safe.

Some folks get confused, they think the F1 number is the same as the A-number. But it ain’t. The F1, that’s just for the students. But the A-number, well, that’s for everyone who’s stayin’ here a bit longer, even the students get one. It’s like everyone gets a name tag at the family reunion, but the students also get a special badge cause they are doing the potato sack race.
Now, I ain’t no expert, ya know? I’m just tellin’ ya what I know, what I’ve seen. But I know this: that A-number, it’s important. It’s your number in this country. So keep it safe, and don’t go losin’ it. And if ya got questions, ask someone who knows, don’t just go around guessin’. That’s what I always say. Like when I don’t know how to fix the tractor, I ask my neighbor Joe.
So, there ya have it. That’s what I know about the A-number and the F1. Hope it helps ya understand a little better. It ain’t rocket science, ya know? Just a number. But an important number, that’s for sure. Like the number on my mailbox, it tells folks where I live.
And remember, this ain’t legal advice, ya hear? I’m just an old woman tellin’ ya what I know. If ya need real help, go talk to a lawyer or someone who knows about these things. Don’t just listen to me! I only know how to make good apple pie, not give legal advice! But I do know this A-number is important for anyone coming to stay in America, even those students with their F1 visas.
