Hello All and @siddu_raj,
Yesterday my wife went to the Mexico Border near San Diego and she successfully got her i94 renewed.
Thanks to each and everyone for sharing there experiences that really helped to follow the route there.
@SidduRaj,
Please follow the instructions given in this forum on how to reach the i94 counter there in San Diego. It really helps a lot. Please let me know for any further questions.
She entered into the Mexico border around 10:40 AM and came out by 11:55 AM.
