Dependent visa for B1 holder

[immihelp]

Hi,

I am traveling to US on B1 visa next month (around 30th April) . I want my spouse to accompany me during my visit . We are not married yet , Wedding will take place next month on 23rd April.

What visa should I Apply for my spouse ? B2 ( tourist or dependent) ? We don't have marriage certificate with us. Can she apply without certificate at this time and can she take visa interview date after marriage and can produce the documents at the time of interview?

Thanks

There is no dependent visa for B1 holders. She can apply for B2 on her own. There is no need for marriage certificate.
