This is where it is confusing for most people - the difference between a visa and status. A visa allows you to board a plane to come at the gate (port of entry) of the US where an immigration officer will give you a status to enter (usually the I-94). Once you are in the US, the status controls even if the visa is expired. However, once you travel you need the visa again. In your case, if you already have status you should be fine. However, we need more facts to answer if you can extend the visa. If the employer is willing to extend (plus you have the number of years left), you can of course extend. I will advise you to talk to a good immigration lawyer at least for a consultation before you do anything.
