我是基於eb1-a的綠卡，可是卡上的category顯示SF1。
-There is not green card code/category called "SF1". So, it is a mistake.
在網上查eb1-a好像應該是E16
-Correct.
（LD的是E19，就是spouse of priority worker)。而SF1對應的是Certain former employees of the Panama Canal Company or Canal Zone Government。跟我一點都不搭邊兒呀。
給uscis打電話問，他們的representive連SF1是什麽都不知道。
這個問題要不要去改呀？
-If you do not use the green card right away, you may file I-90 to get the replacement (return the wrong card with the I-90 filing) and explain what is wrong in the card. You do not need to pay the I-90 filing fee (see the I-90 Instructions). If you need the green card during the I-90 pending, you just need to bring the I-90 filing receipt to the USCIS local office to get the green card stamp in your passport.
See this website for I-90 filing:
