Do you by any chance know what the law is concerning our diplo relations w/Mexico as regards consulates?

Do they have the formal right to open as many consulates anywhere they please?

I think a country has ONE Embassy (usually in the capital city) and then consulates throughout the country...

Mexico has one embassy and at least 43 consulates in the US..

The US has one embassy and less consulates in Mexico...
