It is possible that the case could be because it is an international check. Most banks are not familiar with such and do not know how to process them or give you an expected time of clearance for the check. I deposited a check from Carbon for 4500 and it took 2 and 1/2 weeks to clear when they said it would clear by midnight. The reason is because it was an international and there wasn't any contact info (like a number) for the bank responsible. The check came from Canada.
