The people who oversee international admissions are really occupied because of the application season. So they might be trying to answer ‘important’ questions first and disregard the questions to which answers can be found online until later. So check if the question you are asking has answers somewhere else. Or ask at collegesodhpuch! We have 2 people we know who are currently studying at Whitworth.
Also, sending similar emails to different people does not guarantee a reply. Rather try sending emails to the same person (but know the limit and stop before you annoy them), or maybe call the admissions office?
One possible explanation is that they are dealing with lots of emails and will respond to you eventually. They tend to receive lots of emails at this time of the year. When did you send those emails? If it is not urgent I would wait at least a week before sending them another email.
Also, are you sure that you got the right email address? Try other email address if possible. May be the email address you used is no longer in use. If its absolutely necessary for you to talk to them ASAP you could directly call them. Hangouts lets you call any US number for free.
