I'll jumpstart the replies and others can chime in and correct me..
Credit score impacts your approval chances, but CL is driven mostly by your outstanding available credit and your income. 100K is... a lot. You likely need a very, very large income to be given that kind of CL off the bat with a new CC. Have you been given 100k+ CLs in the past?
I don't know of any CC where you can request a CL in the application process. However, most major banks let you request CL increases once you are approved. Idk much about this process, but I would assume again that they're looking closely at your income and ability to pay.
What are your plans here, what is your timeframe to pay back? Do you own a home / is a HELOC an option or have a retirement account you can borrow against? That's the obvious product here with larger available balances that are still flexible and lowered interest rates b/c they're secured.
