Is simply dropping the maternal family name considered a name change?

[BKW 0]

My husband is from Mexico where it is common practice to use the father's family name followed by the mother's family name on all documents, although verbally you usually just use your father's last name to identify yourself. We were unable to clarify through the USCIS if it is considered a name change to simply drop his mother's last name. His drivers license has only his father's last name but his green card has both just as it appears on his birth certificate. He requested the name change on his application but his interview is August 31st and was hoping to take the oath the same day. Is this considered a name change and, if so, will he have to wait to take the oath another day? He would really prefer to not have both names on his passport, etc., but, for travel reasons he needs to take the oath the same day. Also, can he change his request for a name change on the day of the interview?

Hi -

I am originally from Mexico.

When I filed for citizenship I dropped my maternal last name. It was considered a name change.

In our case, because the oath was at a court house the name change and oath took place at the same time.

My US passport now has only one last name and then updated Social security with one last name as well.

Good luck.

We have patronymic names at Russia, Ukraine and other Slavic countries. Some of us use it as a middle name here, but those who want to drop it, usually go through the name changing process. Our international passports don't have this name, but im. officers found it in translated Birth Certificates and can put patronymic name to the Certificate of Naturalization. So, in my opinion, any dropping is a change.
