urgent-b1/b2 visa-business meeting-intend to visit 10 days before

[asc85]

i HAVE A BUSINESS MEETING IN THE US. hOWEVER, I AM PLANNING ON VISITING 10 DAYS AHEAD AND RELAX AS i AM USUALLY OVERWORKED AND HAVE FINALLY GOT A VACATION.

1. WOULD IT BE ALRIGHT IF I ENTER THE US 10 DAYS BEFORE THE MEETING?

2. I INTEND TO STAY IN A HOTEL BUT MY FRIEND IS INSISTING I STAY WITH HIM. WOULD IT BE NECESSARY TO GET A INVITATION LETTER FROM HIM.

3. CAN MY VISIT BE BOTH FOR BUSINESS AND TOURIST PURPOSE OR WOULD IT CREATE A PROBLEM AT THE PORT OF ENTRY

business visitors are allowed pleasure activity. But you mention your primary purpose as business so you get a B1 stamp on your passport.
not a problem if you enter early. no invitation required. just keep his contact address, phone no. handy.
