You can already do that online(?). Plus, you're legally in the country for 120 days.Overstay fee collection should be simpler with self service migration machines at DR airports. Scan your passport when you arrive. Scan it when you leave to get your clearance printout. If you overstayed your passport is blocked and you can’t board the aircraft until you pay. Paying the fee on line with your credit or debit card would really sweeten the process. Cash payers can scan their passports, get their printout, then proceed to a separate kiosk to pay and get their passports unblocked. The obvious impact here is a significant reduction in migration staff at airports.
