Software Engineering is an interesting mix of practice and theory. On the theory side, you should make a habit of browsing / googling for things that are a good intersection of interesting to you and novel. Be forewarned, some of the common places to get information (like stackOverflow) can be very intimidating.
The standard expiration date for most checks is 180 days (six months) and personal checks are included in this policy. In the United States, banks are privately owned and not government operated so banks do have the right to refuse your deposit if there happens to be any suspicion of the item's negotiability.
Checks are stale after 6 months. The bank may or may not accept the check if it is over 6 months if it is a government check. These are almost always good (money is available to pay the check).Other checks are questionable as to the funds availability. If the chech has a expiration date, you'll have to get the issuer to reissued the check to you.tate of Michigan, check is dated 5-4-2009. Has it expired already?? How long do you have to cash/deposit a State Income Tax Check before it expires?? Thanks!!!
