Re-entry frequency on a B2 visa

[tvenkata]

My aunt has a B2 visa on which she will be traveling to visit me in the US of A. After a few weeks she wants to go stay for two months with her son who lives in Canada. After her stay in Canada she wants to return to the US briefly (a few days to a week) before flying out to India. Are there any B2 visa rules about frequency of entry into the USA that will prevent her from re-entering the USA after her visit to Canada? Hope someone can throw some light on this topic. Thanks.

There is no issue. Most likely they will give her an I94 till the original I94 date when she comes over from Canada.
