本人公民，弟弟有轻微精神病 (在国内事业单位有个闲职的工作)。请问有可能帮他申请亲属移民吗？
-Dependes. Immigration law bars noncitizens from entering the United States or obtaining a green card if they have both of the following:
1. a physical or mental disorder that can be clinically diagnosed
2. behavior associated with the disorder that could pose or has posed a threat to the property, safety, or welfare of the immigrant to others in the public
If your brother has "1" above only, possibly he can immigrate to US.
