Transit Visa

Hi All,
Don't worry about stamping in Mexico at Nogales.
Here is my experience.
Flew to Phoenix and rented a car. It is around 170 miles to the border I drew all the way and took the exit 3 and stayed at Motel8 for 40 bugs.
Next day morning I drew to the border , there will be some persons waving the flags for parking. They charged 4 dollars, I parked the car and walked into Mexico.
Took a taxi(just tell bank name) he charged 8 dollars. Then took the receipt. They accepted US dollars(100). Bank opens at 9AM.
Then walked to the US consulate at around 9:30AM. It is better to take taxi. I forgot to fill the form DS-158.
So fill all the forms DS-156, DS-157 and DS-158 for yourself and also all dependants.
They took Biometrics for my wife and myself and asked to wait for interview.
Both of us together attended the interview at around 11AM. The conversation is here
Officer: How are you doing?
self: good, How are you sir?
Office: good
self:Smile
Officer: Did you change the employer recently?
Self:Yes Sir, Smile
Officer: Are you computer Engineer?
Self: Yes Sir
Officer: Do you have kids?
Self: No
Officer:What is your current Salary
Self:70K
Officer: Visa is granted for both of you, we are giving two days time, but 90% it will be ready by 3PM today , come and check this.
Self: Thank you sir.
We spent sometime there in mcDonalds and then at 2PM I walked to consulate to pick up the passport, my wife waited outside.
One good thing here is the officer did not ask any other documents other than I-129, I-797 approval form, Passport and Employer letter.
He did noot ask W-2 forms, 1099 or pay stubs or anything.
SO I felt this is much , much better than Chennai, in which they will screw you up , if you changed employment and also they don't care about your experience. This stamping is for my 7th year extension.

Good luck for you all and don't be afraid, this is much much better center without much traffic.
Only 23 persons came when I went and all got Visa.
