When I look at the variety of cards - they have given me an assumption of the credit they will lend me - there is nowhere I can ask for say like more. What they allow you to have comes from the CC companies. Is that right.
Yes, when you have had the card for a while you can ask for an increase in the credit limit, very often they give you an increase whether you've asked or not.
We pay the min payment by DD but usually clear it in full. The min payment is set up just in case we forget or are away etc, so no charges will ever be added.
You can ask them to not increase your limit. When we took ours out (listening to hc's advise) they offered us 15k but I lowered it to 5k and asked them to not increase it.
If you start using the credit card immediately for some shopping and pay it off each month, when you need the increased limit they are more likely to agree as they can see you are a good risk.
Usually takes about 10 days to get the card and USUALLY you have six weeks to make the payment after you first use it. Different cards have different terms and conditions but you it should tell on the application.
