本人公民，弟弟有輕微精神病 (在國內事業單位有個閑職的工作)。請問有可能幫他申請親屬移民嗎？
-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.
