Tier2 dependent travel date - 6 months Vignette

[Chase53]

Hi all,

Iam posting this on behalf of my friend, his wife recently got Tier2 general dependent visa in India and the vignette is given for 6 months starting from 1st May. So can she travel anytime before the expiry date or does she need to travel within 30 days from 1st May?

I convinced him that she can travel anytime before the expiry date but he is a bit skeptical and wants a second opinion and whats best place to get great answers than this forum?

Thanks in advance.

Assuming she was issued a 6 month vignette in line with the expiry of her husbands visa.

She can travel at any point before the visa expires.
