My name on GC is like John Doe and my legal name John Doe. But on my passport I have name John Smith Doe (with Smith as middle name). But while filling N-400 application, I forgot to mention this "John Smith Doe" in Section C "If you have ever used other names, provide them below:" Will this be a problem? Should I correct this? How? What is the procedure to send correction letter for N-400? Can I wait till interview to correct this? Or should I somehow correct it now? If I correct during interview will it trigger another name check? Note: My legal name is John Doe. Please advise. Thanks, Newbie001.
