I kept my last name. It's not in our culture for the wives to take their husbands' last names. The kids, of course, will have their father's last name.
I know I got married when we both lived in the U.S., where changing last name is common for most wives, but I wanted to keep with my culture by not changing . My husband, of course, didn't mind a bit - for it's his culture, too. None of the wives in our extended families changed their names, so I'm not the only one..
