I'm a U.S. citizen and I also am worried about overstaying if the lockdown, or enhanced community quarantine, extends in Metro Manila. I'm currently staying in Tacloban City, in Visayas, and I was supposed to leave on the 20th of March, but domestic flights have been suspended so I couldn't go to Manila for my international flight. I had my flights rebooked, both domestically and internationally on the 20th of April. If the suspension of domestic flights gets extended, I'm afraid I'd have to overstay.
