"She is searching for her passport" should be an option.
looking for should also be accepted. actually, it should be the first choice over seeking.
"She is finding her passport" sounds unnatural. If she hasn't found it yet, it should be "she is looking for her passport." In English we don't use the word "find" until the moment she sees it.
I would say "looking" or "searching" for over that any day of the week.
Yeah but now they don't allow "finding", which is also not cool.
"She is searching for her passport" still doesnt work.
