Fiancé's name is wrong in immigration system

[Lalo & Susana 50]

In Chile they issue all documentation as first name, middle name, father's last name and mother's last name. During our immigration process we filled out all the information as my finance's first name, middle name and last name. When he arrived at POE and they put him in the SAVE system they put his first name as his first and middle name together then his last name as his father's and mother's name together. When we got his social security card they told us we should change that through immigration and when we do we can change his social security card. How do we change this through immigration? Can it just be a document in the mail or do we have to go into the nearest immigration office? I called and USCIS told me we had to make an appointment Monday - Friday and go in but I work Monday - Friday and am the only one who can take my fiancé (the nearest immigration office is 2 hours away). Is there another way to change his name to what it's supposed to be or is going in our only option?

Thank you.

This is one of those things I think you will need to go to a CBP inspection location,at an international airport, and show them his passport, I-94, visa in the passport and then have them correct his name to what it is on the visa, I-94 and passport (as I assume they are all the same).

Good luck,
