OK, so this is a pretty basic personal finance question but I swear I tried to google it and didn't find discussion.
A while back I opened a new Chase credit card with 0% introductory purchase APR until like 8/1/2022. Meaning everything I charge to the card has no interest as long as I make minimum payments. For reasons, I've been putting many expenses on this card, including estimated and property tax payments. This card has a generous credit limit, but I don't really want to max it out and take a credit score hit, or raise red flags for future purchases.
So Question 1: Can I move credit limit from one of my other cards to this one without affecting the 0% rate? I can't really think of a reason this would be an issue, except that it would be a loophole allowing me to carry six figures of debt for another 9 months. (that's not my plan, just the logical extension of allowing me to consolidate all my Chase credit into a single 0% card)
Question 2: When do I have to pay this balance by? I know in my heart the answer is 8/1/2022, but is it possible I can squeeze another month out of it since the statement closes then? Just looking for confirmation, I don't need to delay so I'm likely to just do the safest thing and pay everything before the expiration date.
Also, I know the best way to an answer is to ask Chase, but I always feel like eyes on accounts may trigger additional review which is no fun
