On my new CSP, the site says payments due the 17th of the month, so I expect the first statement will close 7/20, meeting the $4K spending for a 100K point bonus. I'll plan virtually no use in the next month, then heavy travel use in the month and a half after 8/20. My general preference would be a closing date of the 12th (due the 9th): after 8/20, if I make that request, will I safely have the next statement close 10/12 rather than 9/12? Or should I make the request between 9/12 and 9/20? I'll be overseas and worry about remembering it. I have a vague memory from some years back that I asked for the change the day before the new target, expecting it to take effect the next month, and instead the statement closed right away giving a short statement period.
