Here is my experience (H1B). This was my second H1B stamp.
Make sure you take your resume and tax returns with you. They ask for this at Nogales. Also, fill out the DS158 even if you know it is not needed for H1B. Another Nogales quirk.
I was asked very simple questions. She looked at the resume and made some comments. How many US visas have you had? What do you do? Ok, we will issue you the visa, come back at 3:00pm.
No need to get any permit to go to Nogales.
The most gruelling part is the getting back into US. The issuing of new I94's is *very* slow. Make sure you are one of the first ones at the consulate to get back the passport so that you are at the front of the line at the border.
