Hi.I requested visa for my parents online and because there is no any Bio-metric center (VAC) in our country ,they had to go to another country to do bio-metric test .after it done I got a message about insurance for them that they have to get an insurance for at least 365 days and 100,000 coverage and above and its so expensive .I did mistake to choose between super visa and multiple visa .can i cancel or change the supervisa to multiple without doing biometric test again ?
