B2 Visa - Port of entry requirements

[anipal]

My wife and myself both have a valid US B1/B2 Visa that we got from the Mumbai, India US Consulate. We have both been to the US separately multiple times on business individually. We have never gone as tourists before.

This time I need to go on business for 1 week. I plan to extend this with 1 week vacation after my business meetings for visiting various places (Washington DC, Niagara Falls, New York City etc.).

Also my wife intends to accompany me as a tourist for the full 2 week period.

Can we travel on our existing B1/B2 Visas or do we need new Visa? Do we need any other supporting documentation at the port of entry apart from my business invitation letter?

Immihelp,

Sorry I may have titled my post badly. But my key question was the first one: -

Can we travel on our existing B1/B2 Visas or do we need new Visa?

Thanks,
