请问八老师，我儿子（13岁）有自闭症，语言非常有限，还有行为问题，感觉参加不了面试，请问能不能为他申请免面试，如何申请。非常感谢！
-Probably he may have to go for the interview and you need to go with him, and then explain it to IO (bring the doctor's diagnosis, if any). I don't think it is a problem.
There are some situations that the I-485 applicant can apply for interview waiver. See this USCIS's oplicy for interview waiver requirements to see whether your child meets one of them:
