Oops sorry. I applied for written authorization along with my trv. Hence sent a follow up in webform for trv application mentioning I am exempted to travel restrictions.
If your request for authorization was sent thru email, and already past the 14 days..I suggest you check with your MP. They should be able to follow up or look into your application status. There is also a page and a group in facebook where you can find a mail that can be sent to your MP. Please check Faces of Advocacy group or page.
