父母2004年第一次来美国的时候，当时我还在读书，也没想到以后会留下来。老爸是党
员，当时办签证挺难的，填的申请表上的那项是否是党员的选项，我就选了个不是党员。
现在打算给父母办绿卡，老爸的这个选项，我应该选是，还是选不是。
-He should tell the truth and then, write a statement to explain why he joined the Party (e.g. for employment, promotion, etc.). You can Google to find the related sample letter or artilces.
如果选了是，肯定会查到以前签证申请表上的非党员的选项吧，会有什么后果吗？
-I don't think his non-immigrant visa application materials more than 10 years agon is still present in the system, and I don't think USCIS will check that case more than 10 years agon for his immigrant case today. So, it is not an issue.
或者还是选非党员？
请问8老师，我应该怎么办？若谁有过经验，请告知一下。中国人都挺不容易的，等绿卡的折磨只有自己知道。
