How many citizenships could my child have?

Hi all,

I had this interesting thought experiment about how many citizenships my future child could have….

For context, I’m born in Thailand to a Thai mother and an English father, therefore I have Thai citizenship and I’m also a British citizen via my father (although I’ve never lived in the UK and have only visited once to see family). My girlfriend is Filipino.

Let’s say in the future my girlfriend and I have a child who is born in another country, say, America. Technically, doesn’t this mean that this child would be a citizen of Thailand, the UK, the Philippines and America??

Interested to see if you guys have anything to add.
