Diferent last name

[latininNJ 1]

OK, I have a friend which is trying to bring his wife and son to the US.

He's a US citizen, he was born in NJ, but was sent to Ecuador as a child, because his mother, a single mother, couldn't bare the costs of a child so she sent him to her sister's home, his aunt, although his mother registered him in the US as Michael Perez, his aunt also registered him in Ecuador as Michael Castro, so here's where the problem is; his US passport and SS card has Michael Perez, but his wife and son have his other last name, which is Castro.

Will there be a problem when filling I-130 for his wife and son, since they have his ecuadorian last name and not his US last name? Or does he just put in "other names used" section his ecuadorian last name. How should he proceed?

Thanks.

He puts her Last name "Castro" as her name, and her Maiden name as other names used.

NOTE: as soon as his child enters the USA and gets green-card he should be able to file an N-600 for the child's US Citizenship.
