Standard UK Visitor long term visit visa selection issue - new application form

[Meghgum]

Hi,

Am trying to apply for a long term standard visitor UK visa from India for my mother. I have completed till the Declaration section. But till here no where i found any option for the visa length (6 months,2 years,3 years etc). I want to apply for a 2 years visitor visa so that she can visit UK multiple times to visit my elder sister and her family in the UK.

I am applying through the link https://www.gov.uk/standard-visitor-visa

Will i be getting an option for the visa duration in the pay tab? or am i using the wrong link

Thanks

Also three years back she had got UK Visa for 6months and visited UK for a period of 3 months

Once you submit the application, you will then get the option to choose if you want to apply for 6months, 2years and so on.
