Originate (from)

No, it is not required. It is not appropriate to end a sentence with a prepostition.

you certainly CAN end a sentence with a preposition - that rule is a lot of tosh .."up with which I will not put" (as Churchill is reputed to have said to show how silly that "rule" is!)

but the point might be moer that "originate" really means starts from -so in a way the "from" seems a bit redundant or tautological to some people.

"This is the place where they originate." would be fine, I reckon - but you DO hear Brits adds the final from, especially in conversation.

So it is a matter of where you originate? What about Americans? Is there a difference between them and British people?

My t

As I said - the word itself might be seen as including the meaning "from" - and I've seen it used as I suggested above - without "from" in some cases -
but also I've heard it used as you say.

I don't think it is a US / UK issue . You should follow your teacher's guidance!
