One of the best things about homeschooling, is the fact that you can have school at any time or any place.
As far as graduation, if you join an organiztion, they may provide certificates for you, or you can make your own. Getting into college is really no more difficult, just make sure you can provide a list of couses you have taught or they have taken online or off. They will still have to take the same tests to get into college. Keep a record book of some type for assignments and grades, and even a sampling of work that your child may do.
