Maybe, but since you already have a biz card you could offer to shift credit over from that card. I would avoid dropping CLs with Chase because once you drop it you're stuck, Chase won't give it back to you. Also, like
@deide71 says you need to pay attention to your credit utilization ratio. As close as you can get that puppy to 0% the better you are. Check Credit Karma to see where you're at. As someone just starting out this part killed me at the beginning because meeting a minimum spend on a card drove my utilization to like 30-40% and my credit score would drop like 40 points and take a few months to recover. If you have
lots of available credit you can drop CLs and not be affected, if you don't you'll want to tread lighter when considering dropping CLs.
