I bought a MacBook air m3 last month from US and now when I plug it in charge, I get a little electric shock from the metal body, is it normal? It's like a little vibration feeling. And when I remove it from charging then I do not get the electric shock.

I do not believe this is a problem with the Mac or its charger, per se. Rather, I suspect it is a problem with the electrical wiring for the outlet/receptacle.
Personally, I have experienced the electrical tingling described with my own Macs on rare occasions. When it happens, it’s tied to the outlet. I have used different computers and different adapters on the same outlet and experienced the problem, when those same devices do not result in a tingling plugged in annywhere else.
You need to ground the charger. You can use Apple’s power extension cable for that, I believe they sell them with country-specific 3-prong plugs.

No, it's not normal. Either your mains socket, charger, charger lead or Mac are faulty. Stop using the PSU and take it to an Apple store with the PSU and cable. You can charge it via USB with another charger, although it will be slow.

You're absolutely correct. It's pretty common, especially with the U.S. adapter. It's also harmless.
