I got my H1B visa stamping (renewal with different employer) done successfully at Nuevo Laredo. Want to to share my experience to forum.
Recommended to get Mexico visa stamp. I visited Mexican consulate in my city. Key documents are I797, Pay slips and address proof required to get Mexico visa. The entire process should take around 2 hours if you visit consulate in your city. If you are not close to Mexican consulate please call help desk they should guide you what needs to be done.
