Possibility of having 2 valid visas,B1 and H4

[suneeta]

I got my B1 visa stamped recently from US consulate. However, I might have to go for H4 visa appointment with my husband, as he has got his H1 approval.
I wish to know if my B1 would be revoked when I go for H4 stamping, or it would still be valid.
My company would be sending me to US on business visit soon. In that case, will it be a problem at the port of entry due to 2 valid visas.

you cannot be in more than one valid visa status at the same time. If you acquire H4 status, your B1 status will cease to exist.

Unless B visa got cancelled by consulate, it is still valid. Sometimes(not always), consulate puts cancellation stamp on old visa when you obtain the new, then, old visa can not be used.
