Be prepared for crappy service and irrational policies. That's HSBC! In general they pretty much act like they could care less whether they have your business or not. They effect a total sub-prime mentality.
I have a Direct Merchants Bank/HSBC card issued at CL=$1,000 about 8 years ago. I did receive two auto CLI's=$500 each, the most recent now over a year ago. They also jacked my rate as well, too. Now you cant ask for a CLI and you cant ask for an APR reduction. So the card is SD'ed and buys me a lunch once a quarter. (For all I know I am at the max CL for that card now. But how would you know - you can't get any information from them!) Worst part is I am sure they just don't care. And don't let an HSBC issued card go unused for too long. They will close accounts for inactivity in a heartbeat. Happens all the time.
