No Passport? Don't cross.
[QUOTE=DCups;2561016]My passport is in the Philippine Consulate in San Francisco being processed for visa there so I won't have my passport. What can I expect at the border coming back to USA? Thanks.[/QUOTE]Trying to cross back into California without a passport may subject you to extensive delays.
OTOH, you probably won't have any trouble driving into Mexico; about 99% of the time you drive right through. The exception, getting pulled into "Secondary", is about import duties. They may not even ask for ID.
Border wait labor day weekend
Heading to Tijuana on Saturday and going walk across as usual. Hopefully the pedestrian line will not be zoo coming back the evening.
