Spring is their busiest time; all the college students heading out-of-country for the first time at the end of the academic year (usually May) clogs the system.

9-3/4 years is fair enough to keep from stressing out. But if you have no specific dates for travel, you can be late. Nobody cares.

"Don't worry dude."
