How long would it take me to get PE?

Hello everyone,

I have a BS in mechanical enigneering earned from ouside the US and a PhD in mechanical enigneering earned in 2020. Since 2020, I have been working as a materials engineer at a large corporate where I use microscopes to inspect the surfaces of some components to understand the root-cause of unwanted phenomena such as wear and corrosion.

In my case, how long do you think it would take me to get a mechanical engineering PE?

Thank you for your responses in advance.
