FNU listed as given name

My husband’s visa from US embassy in Mumbai has his given name listed as FNU and they joined his given snd surname as a last name. Nowhere on any documents submitted including the passport they put the visa in does it say FNU. He’s coming home in less than two weeks. I’m worried this will be a problem on his green card and any subsequent documents like social security and drivers license. I saw that some others have had the same issue. Any suggestions?
