Getting the full amount of a check immediately can take some work, but it's a straightforward process. If the check is under $200, your bank is required to make the funds available immediately. The same usually applies to government-issued checks as well. If your check is over that amount and you'd like to access all of the funds immediately, get it cashed at the check writer's bank. They should be able to give the amount to you in full, and you can then deposit the total amount into your account.
