Last Name Issue

[snellog]

Hi,
My in-laws don't have last name in passport and hence we got the visitor visa with First Name as "FNU" and Last Name as "First Name" (As per US Consulate).

I am trying to book tickets for which I need to enter First Name & Last Name as per passport. Since they don't have Last Name in passport I am keeping it empty. But the system is not ready to accept spaces in Last Name. Please let me know what do we need to enter in Last Name when we don't have last name for booking tickets.

Thanks,
Suri

Just go by what is there in the visa stamp.

Real first name goes as last name and FNU as the first name.

Please follow as given in visa and book the ticket accordingly. I had a problem at Chicago airport and was not allowed to board the plane to Dallas as the ticket name and the visa name did not match. I took the help of airlines people who made a revised boarding pass and allowed me to travel to Dallas.
