8老师您好，先谢谢你之前的回复以及宝贵的建议。
这两天我们也在咨询各个方面的意见，也有建议我们去上诉的。因为重新申请的总费用高于$700, 而且要重新背景调查，因为背景调查是没有时限的，也不知道要等多久。。
当然也有建议重新申请n400的。想问问8老师能给我们讲讲关于您建议重新申请n400，主要有哪些原因呢？
先谢谢啦

here is what IO said
"You filed N400 on 22JAN2016." ""Here N400 page one states you are at least 18 yrs old and have been a PR of US for at least 3 yrs..... and your spouse has been a US citizen for the last 3 yrs AT THE TIME of filing your N400."
"You should wait to at least 19APR2016 to filed N400"

my wife got her green card since 18Feb2008, USCIS received her n400 on 20NOV2012, she passed her n400 interview on MAR2013, and become US citizen 19APR2013. AT THE SAME USCIS FIELD OFFICE!
请问一下各位前辈有试过上诉吗？
还有哪些途径呢？thanks
-Yes, you can file I-290B for motion to reopen or appeal. The filing fee of I-290B is $675. So, I suggest you to file N-400 again, not I-290B.
