The Apple Card pre-qual is basically 100% solid, so you can definitely get that if you'd like. Amex pre-quals are also solid, and I've seen DPs of students getting Golds and BCPs quite a bit, both on here and Reddit. If I were you, I'd go for a Gold, wait a few months, then maybe another Amex card. And after that, Apple Card, since the preapproval will always be there. But honestly, Amex's MR system can be quite limiting if you don't have the co-branded Plat cards and you don't have the flexibility for expensive aspirational trips. I'd suggest the CSP, but no idea if you'd be approved with such a thin profile. Getting a CFU/CFF might be a good start, then wait a few months and CSP, if you want to go down the Chase route.
I am an old man (Ha! Ha!) who had some issues several years ago and I am rebuilding, too ("too" in that someone else has stated that he/she is rebuilding). I find it impressive that someone your age (but, age does not speak to experience....and there is A LOT to be said for experience) is so in-tuned to this. I wish that my generation (I am 54) would have put more emphasis on credit cards and personal finance. Anyway, well done so far. And being an AU is fantastic. It definitely gives you a leg-up on everyone else. The fact that you have indeed acted responsibly speaks volumes. You were given an opportunity and have run with it (vs. mucking it all up). As others have stated, I would suggest that you venture down the Chase / AMEX eco systems. These two companies seem to be at the top of the boards, both have AMAZING Reward programs (question is - seems like you CAN INDEED take advantage of these programs at this point. Will you?), and both seem to have amazing customer service. To be fair, Chase / AMEX are not the only games in town. I would also suggest that you look into some of the Credit Unions. I just became a member of the Navy Federal Credit Union (thank you to my amazing little bother, who proudly served this country for 27 years!!!! Thank you for your service, you little *shish*! LOL) and they seem to be awesome. There are a few others (PenFED, USAA, Redstone, et al). They offer very competitive rates for auto loans and home mortgages (might not be a thing for you at this point....but in a few years who knows, right?). With Chase, be aware of the 5/24 rule. That is that you have applied for five cards in the last 24 months. There are lots of different "experiences" on this as to what "cards" count. This does not seem to apply to your case at this moment in time, but be aware of it so that SHOULD you decide to explore both AMEX and Chase that you do so in an intelligent manner (read: that you are aware of the Chase 5/24 rule). Welcome to the forum. Enjoy the journey!
