Dating someone of Persian culture

Tweet

I recently met a Persian man who I have feelings for. I am very open to dating people of other cultures but his family has only recently come from Iran and I do not know very much about Persian culture. I am sure that if things are meant to be they will work out but does anyone have any tips to help me avoid doing anything that he or his family might find offensive? Or just some general information on Persian culture would be nice so I know what to expect. Thank you for any advice you can offer!
