I recently applied for a visitors visa to take a PLAB exam on 6 July; my visa was issued to expire on 4 July!

I contacted them via email and phone and all they did was tell me that they escalated the issue; it has been 2 weeks and no one contacted me.

  1. Can this be fixed without applying for an extension?
  2. Can it be fixed while I'm in the UK because I need to go there to audit some courses?
  3. If I apply for an extension, will I be able to travel to and from the UK for the extended period or it will extend my ongoing visit only?
