How long after you get a wound that requires stitches can you actually wait to get stitches?

18 hours. Up to 18 hours. If the cut is on your face, up to 24 hours.
Depends. It is usually best to be seen right away. If the wound is clean or cleaned up, and depending on the locatin on the body, some physicians will allow up to 12 hours. Some longer. If the wound is dirty, a puncture or contaminated, get seen right away. There should be very few reasons to delay closure of a wound. Be very careful and cautions and err on the side of immediacy.
