Yes Yes

4 business days. I know this because i recently had to ship something there via UPS Ground and that is exactly how long it took.
It means have it delivered via mail, UPS, FedEx, etc.
Yes. Normally shipped via FedeX, or UPS.
Personally I would ship it via one of the major carriers - FedEx or UPS. If you send it via the US mail you have to declare the contents of the package - which in my view is NOT a good idea.
It will take approximately 2-4 business days.

Veterans Day is a federal holiday so all U.S. post offices are closed. But if they ship via Fed Ex or UPS, etc. it might be possible.
Its always a risk. Just ask yourself which is greater, your need to ship the ring or the risk and consequences of the ring never making it there.
