Should I give lei to my mainland professors?

I moved away to mainald for school but despite that I do bring my aloha around.

I am mindful of other people's cultures but also love sharing mines. I am thankful to some of my professors and wanna give them a lei at the end of the semester. And even though it's not their culture, is it appropriate of me to do that? Idk I'm asking here because anyone might have some insight to the similar experiences I had. Thank you.
