US H1B and H4 fingerprinting, scanning: Minor cuts, cracks on the hand

Getting your final stage of US H1B and H4 Visa stamping maybe really scary due to the Interview and OFC process. OFC process is really straightforward, but one thing one needs to take care is that your fingerprinting should be successful. Any major cuts on your fingers can result into rejection/delay in fingerprinting process.
1. Make sure you don't have any major cuts on any fingers on both the hands.
2. Any cuts at the side of the fingers and not on the fingerprinting areas should not be a problem. My wife had a cut on her finger, but it was on side of the finger so it didn't cause any issues.
3. Minor cuts don't cause any problem, but if you have few days before the OFC make sure you treat them and they are healed.
4. Cracks on Fingers due to dryness, or due to winters is not a problem, but keep applying moisturizer till the last moment your outside the Consulate for OFC. No medicines allowed inside the consulate.
5. When you schedule the appointment for OFC from that day take care of hands, especially ladies so they don't end up having major cuts on Hand. If something happens, treat them by taking to doctor.
6. Incase your really fail in fingerprinting, they issue a yellow slip and ask to come back once your cuts are healed.

US H1B and H4 OFC is very simple process, all they do is take fingerprints four fingers on left hand and four fingers of right hand and finally fingerprints of both the thumbs placed together. This is followed by taking a digital photograph.
