How long does it take to cross the border by car and what is the best time and day of the week to do it?

Well, through otay's table you enter and leave early the times that I have done it, it took 15 to 20 minutes to enter

Thank you very much, how nice. But he only wanted to cross once to the US and once back. I go to the. What time is the best to cross?

There are many variables, usually 1 hour although it goes up to 2-3 hours normal when there is a regular line and 4 hours when the line is very heavy, it is advisable to leave your car in a parking lot of the otay la usa and cross walking towards Mexico , use free taxis or yellow or uber taxis for more comfort, so that when you cross back to the US you cross the pedestrian line that you can usually cross in 10-15 min on weekends.
