Be advised Chase tends to NOT issue that many new accounts within a short period of time to any "poor college student."

Seeing you just got a Chase Freedom with low credit limit ($3K). If I were you, I would think very hard and carefully the next Chase card I'd apply. CO/UA/Sapphire are all Chase cards. There's also a big chance that you'd be approved, if ever, for a card with much lower bonuses (due to your short credit history/score).

Don't forget to factor in to get a card that you can for sure meet the spending requirement in time.

Good luck!
