You get to travel in many countries without securing first a visa in Manila.
I’ve been to China and South Korea on a red passport. I’m looking forward to
travel in the Schengen area, and guess what, except for Amsterdam and France as
ports of entry, I don’t need to secure a visa first. A few thousand pesos were
saved, not to mention a lot of effort and time going to the appropriate embassy
and perhaps do interviews. Some countries like Japan require a visa but the
fees are waived and the procedures are simple. If you use a red passport, most
likely you don’t need to secure appointment with the embassies first. And most
of the time, there is no need for a personal appearance because things will be
done through your liaison officer.
