B1/B2 vsia:Change of citizenship

[doc.panky]

Hello everyone,

I am an indian citizen living in Australia. I have 10 yr multiple entry b1/b2 US visa stamped on my indian passport. Now i am applying for Australian citizenship this week. I am travelling to US in April for a business purpose and will stay there for 3 months. My understanding is that i can stay in US with my current indian passport and the visa for 3 months.

Now my query is that if by March, i get the Australian citizenship, will the previous B1/B2 visa is still valid ? If not what are my options. Please advsie.

Thanks
