Do you happen to have a post for her mother?

When did her and the father first apply for immigration to the US?

After that... when did they renounce their citizenships for US citizenship?

Do you happen to have a post for her mother?
We'll it's obvious YOU didn't read the article. Kamala Harris’s mother, Shyamala Gopalan, was a citizen of India when she arrived in the U.S. in the fall of 1959 as a Master’s degree student. It is unclear whether or not she naturalized as a U.S. citizen before her death in 2008.

When did her and the father first apply for immigration to the US?
I would presume for the father the date given in the article.
Her immigration would have been granted automatically by law upon her birth to ALIEN parents noticed on her birth certificate.

when did they renounce their citizenships for US citizenship?
Who said anything about citizenship being renounced?
