Hi,

I was the UK sometimes last year with a 6 months multiple entry biz visa.I could not travelled with for the second having gone on annual leave for the year before its expired.

I intend to travel sometimes next year.What do I need to do?Renewal or apply for another visa?What duration is most desirable?I intend to make it self sponsor,stay in hotel,with and or without invitation.
My passport is still very much valid and my employer is willing to give confirmation letter.

With the nature of my job,I can only travel or have the chance once in a year while on annual leave.
