Validity of a B2 Visa

How long is a B2 Visa valid

[kabkaba]

Depends on Visa officer. There is no fixed limit. Max is 10 years. If visa is issued, it will have expiry date clearly mentioned. This is the last day one can travel to US.
Are you asking about how long a person can stay in the US as a visitor?
