Rio grande ,the bridge over the border. El paso,Texas.
My business trip on this time.Departed from L.A. to Dallas,TX and change Plane to The Mexico.Arrived San luis. Do Work, first mission was completed.Departed to Mexico city, and change plane to the ciudad Juarez.Do work, Last mission was just completed. Third mission would be to go back Home.Hardest part of this trip is to across the US border.Because, When I departed from Dallas, i must return I-94 form.I-94 form known as immigration card. when i return to US immigration(usually boarding gate) , it means, i exit from USA.If i re-entry a USA again, i can fill the I-94 form in air plane.i can fill the I-94 form in air plane, if I want to re-entry a USA again. Yes I can , Obtain this form free and easy, If it is on a plane...if across the border from USA side by car, you can keep I-94.consider it is that, you are short trip to mexico.You don't need to fill the form, when re-entry.this time, i must go to immigration office. because,I must have i-94 form,before across the border.
