真是抱歉，考古了一下，发现几年前问了您同样的问题，您回答了，可是我忘了这码事儿，所以今天又问了一遍。实在是太抱歉啦。您上次的回答是file I-90. 请问现在还可以file I-90 更正吗？
-Yes, you still can file I-90. But because your green card has been issued for a longer time, you had better call USCIS to see what they suggest before you file I-90, ESPECAILLY you may ask them whether the mistake on your green card category affects your N-400 or not if it is not fixed. If it does not affect n-400, then you do not need to do anything. Because it was USCIS's mistake, they may give you compromise (they have all of your record, anyway) and thus, you may just file N-400 and do nothing.
By the way, it may take a 16 months for USCIS to process your I-90 and you may need to pay the filing fee.
