Dear Customer,

PLEASE DO NOT REPLY TO THIS MESSAGE. THIS MAILBOX IS NOT MONITORED.

Your UK visa application is currently under consideration at the British Embassy Abu Dhabi.

We are aware that you purchased the priority service and I can confirm that your application was assessed ahead of other visa applications. Unfortunately the processing of your application has been delayed while we undertake further assessment. This means that we will be unable to make a decision within our published customer service standards.

We will notify you when your application has been concluded, and you will be contacted by the Visa Application Centre when your documents are ready for collection. Please do not go to the Visa Application Centre before they have contacted you.

Please avoid making travel arrangements until you have collected your passport.

We would be grateful if you could keep your correspondence to a minimum during the consideration process. If however you need to contact us or would like to track the progress of your application, you can do so via our International Enquiry Service at www.gov.uk/contact-ukvi-outside-uk

Kind regards,

UK Visas and Immigration
British Embassy Abu Dhabi

It means the Case Worker needs to verify certain issues in your application which require further checks and no one can guess what those checks relate to. As you have paid for a priority service the HO are required to notify you to advise that they are unable to meet their normal service standards. Most applications submitted in Dubai (non priority) are currently decided within 120 days.
