Incomplete First Name on my green card

[oliTwist]

Yesterday, I received my much awaited Green Card by post. But to my dismay, it has incomplete first name in it. My first name has 5 words in it( xxx yyy zzz aaa bbb). I generally go by bbb as my first name. The card has only (xxx yyy zzz) printed on it and no aaa bbb anywhere.

Does anyone know what I should do in this case? I am very disappointed with the card printout, as the complete name is what I was expecting. I know during Citizenship time, we can change the name anyway we want to, but in the mean while , what should I do?

Any suggestions is highly appreciated. All the best for folks who are waiting..
