If the family is accessible I've found this to be a wonderful proxy for compatibility. Is their family structure how you'd like yours? Do you get along with and easily make friends with other family members?
It's a good sign if your personality is compatible with the family and their way of life is what you're looking for.
It's of my top indicators, I've rarely found people that strayed very far from their family in personality, hobbies, and life outlook.

In my experience, that's generally true except for people who moved to a different country at a relatively young age (or just after high school) and stayed in that country. So in the case of OP, if her family lives in Iran and she's in the US, it's likely she has a very different life outlook and cultural view than her family.
I suspect that people who move far from their family of origin are, on average, less compatible with their family. If you are generally compatible with your family and like being around them you're more likely to prioritize living near them when making life decisions.
