No, you don’t have to visit the embassy, but the policy is that you are supposed to physically be in the jurisdiction where you are applying for the evisa. You bill might be enough to convince them that you are physically there, but there is always the chance that they ask for more proof. If they do, and learn that you lied, that is problematic. Why can’t you apply via the evisa system though the embassy wherever you are now located?
