Credit Union credit card

Answers are yes and yes. Credit card lenders can do basically anything they want..reducing or closing credit lines are commonly affected when your debt to income ratio is too high, bankruptcy or missed payments on other cards. Credit cards are unsecured and they will shut you down if you appear to be a risk.

I asusme it depends on the state. It also probably depends on the terms of service of a lending contract. I know that there is probably some clause in the credit card contract where they can "cancel an account with or without cause." I don't think they should be allowed to do this without a notice though. I think that's wrong.

PLEASE, stop posting your assumptions. If you do not KNOW the answer, or if you're just agreeing with the person who has already posted, don't post.

Had that happen to me, had a chase card a long time ago with a high balance but was always making payments on time. One day I went to use it and it was declined and thats when I found out the card had been cancelled.

The same thing can be said about interest rates too. Anytime the credit card company wants to, it can raise or lower your APR.
