I wanted to know what’s the ruling on marrying someone outside where you’re from like an iraqi marrying a lebanese and how to go about that if the family isn’t allowing of it

Yes it’s permissible provided conditions (eg they’re Muslim etc) are found. It will have challenges but one way is to seek help of Ulema and Family relatives who can influence parents perhaps.

It’s important to note that invariably there might be cultural conflicts and both the husband and wife need to be patient and know what kind of issues may face them
