That means, for example on my first entry, I can extend the 60 days to 90 days instead of doing a border run? - or it can only be extended by 30 days after the "Must be used by" Date?
Ahh yeah, that makes sence. Now I understand. Ok, then it makes more sence to get the 45 day entry stamp and extend it for 30 days. Thanks a lot for your explanation.
