How do they decide credit limits for your first credit card?

I just applied for my first credit card ever yesterday, and I am hoping to get a credit limit of at least $1,500. I have no credit history whatsoever, I don't have to make a house payment, no dependents, and I make $12.10 an hour working 35-40 hours a week. Would all those factors contribute to a higher or lower credit limit, and do you think I'd be eligible for the $1,500 limit?

Every creditor is different. They look at your history and capacity to pay.

If you don't get what you want, use it for 6 months and pay it off every month, then call customer service and ask for a line increase. Keep asking every 6 – 12 months.
