Suppose I have H1B which I never used

[suwsku]

and it's still valid for almost 2 years.

If, say, I find another employer in a few months, can I use the visa that I have now?

If so, can I start working for that employer once he files a new petition, or do I have to wait until the new approval notice?

What status are you in now ?

You can try to move existing visa to the new employer if it has not been revoked by the employer. If you are not working for them...they are supposed to revoke it.
The process for moving to a new employer with existing visa is almost the same as applying for a new one except that you are not subject to the annual cap of 65K

Considering that you have the old employer stamped on your visa...it will cause confusion at the airport or POE and they might send you back

Its better to file a new application since you are not in the US

I believe you can enter as long as the visa does not expire. But make sure to check with your company lawyer.
Also make sure you have a real job/work when you enter.
