What is the fastest way to renew our passport?
If your passport has expired, you probably need to stay where you are until you get a new one. There are very few border posts of any country that will admit a person with an expired passport, and even fewer airlines that will carry them even if they are going home and are sure that the passports expiration wont be a problem. Of course, you havent told the whole story here, so if you now will add a comment that changes the nature of the question and the issue, you should have done that on the first try.
