Jakarta or Taipei? You previously mentioned that the evisa system for Jakarta has been delayed. For Taipei, they told me when I enquired that applying in October is fine as they're not moving over yet but they probably will eventually.
For the time being, but they might still be required to switch eventually. I wouldn't hold it off too long if wanting to apply there. Anytime in October seems safe but who knows, they might switch over in November or December?
