Does 1/30 mean 1 Chase card per 30 days? Can you bypass that by going for 1 biz and 1 personal?
If you've gotten any Chase card in the last 30 days. There is a 1/30 rule guideline (1 card every 30 days) for the business cards, so you want to wait until you're at least past that. You'll get a denial unless you haven't gotten ANY (personal or business) Chase cards in the last 30 days.
So firsr biz then after approval a personal should work.
