Fly to Vietnam or Taiwan on a one way ticket and apply online from there. Could take a couple of weeks at most, but that’s your best bet. If you have the income and time, it’s a good option. Make a vacation out of it.
I’m very sorry to hear that. I guess he will have to rebook his flight :( I also didn’t get mine. They said because I’m leaving mid March to expect it first or second week of March…
