temporary maybe because its a probation period, and it goes up as you pay on time each month.
possibly because you never had any relationship (checking/savings/credit/money market/investment/loan, etc) with chase.
you could call recon to have it raised higher.
How much income did you put?
$15000-20000, About $10,000 each is expected from job and from my scholarships/grants annually.
low income might have been the cause of it.
just call recon.
Congrats on your recent approval! Should be a solid 6k within 61 days if you do the 3x cli.
This card is in my list for next year. Enjoy.
