Australian citizenship with US Green card and passport change

My husband received CR1 visa to travel to US. His citizenship will change from Indian to Australian next month and he will be receiving his Australian passport.

Does the change in nationality matter once he receives his green card?
Thanks.

Hi @RCA

I don’t understand your question clearly.

What exactly are you worried about after getting a US green card?

His CR1 visa is stamped on his Indian passport. Next month he will have his Australian citizenship ceremony and get his Australian passport. Does it matter that his visa was stamped on his Indian passport and his nationality/passport is changing?
Thank you.

Hi @RCA

I don’t think he can travel using the Indian passport once he gets an Australian passport.

As per my information, he will need to surrender Indian passport and hence the visa too.

OK…Thank you. Once he comes to US,the green card is mailed. Do you know if it matters if his passport changes,once he gets his green card?
Thanks.

Hi @RCA

I do not have answers to your vague questions. Please be specific.
