Network Administrator - What Visa?

Hi everyone,

I'm looking to work in the U.S and I'm wondering if it's at all possible to apply for a Visa under my type of work. I would be suitable for Network Adminstrator/Network Specialist/Network Analyst. My background is from Networking in the I.T field. Under the TN Visa, I only see "Systems Analyst" which is not even close to what I do, so that option is doesn't work for me.

Is there any other Visas that may apply? H-1B or H-2B? Will any of those two work in my favour?

Thanks everyone

Dan
