International drivers are allowed to drive on US roads as long as they have a valid license in their own country. In particular, Filipino drivers are allowed to drive on US roads without any extra paperwork.
But also, even in the USA, we have 51+ different licensing schemes in the US. We already accept that if you have a license in one place, it's good in all the places.
Indeed. I can rent a car and drive in the US, despite having learnt to drive and only having a driving license from a country which drives on the other side of the road.
