Though I have lots of cards, I probably have a good credit rating. That's because, following advice in this forum, I usually pre-pay much of the balance before my statement closing date.

Given this payment pattern, how often can I apply for a new card without lowering my FICO score significantly? I'd like to apply (or re-apply) for around 3 cards right now, but assume it may be better to space the applications over several months. Is it OK to apply for one card per month, say?
