For anyone who’s interested, I spoke with two of my credit cards, Citi and Capital One.
Citi had what seemed to be the better program, a two-month “freeze” (no payments, no accrual of fees), and said I could call back if I didn’t have another job by then.
Capital One waived fees and finance charges for three months, but said that I needed to continue to make minimum payments (which would come straight off the principal).
