TN for Mexican Engineer

[viajero]

Hello there,

A question just to know if anyone there can help me out,

If I already have a Visitor-Tourist visa, can I change my status to TN visa in the USA or I have to flight back to Mexico City.( A web page says something about a Form I-129)

I am looking for nurses from Mexico interested in working in the US. We can sponsor visa and provide employment. Please contact at Amy.Warren@emedrn.com
