Usa – Entering the US twice within a week with the B2 visa

The special rule on visits to Canada and Maxico, "Do not reset the clock" applies, as far as I know, only for the visa waiver program and not for travelers with a visa.

But even if, I would not see how it would cause you problems since then final The US leaves after you only about a week first entered. It does not matter if a clock is reset or not, this is definitely an unproblematic short visit.
