Hardworking father , no criminal record, lets bring my father back home

On April 17th , 2018 ICE took my noncriminal record , hardworking father from the entrance of his house , My 5 years old sister was present and watched as our father was snatched and put in a van with a bunch of strangers ,My father has 5 children who are all american citizens , 2 grandkids sofia who is 9 , and a grandson who is 5 months and who he loves dearly ,  My father has been in the U.S. for 30 years , he has a legal job at Carol Woods Retirement Community and he has been there since 2001 , , He has his license , he payed taxes every year , he has had no criminal record , and he's been in the U.S. for 30 years , He did everything legally while being here illegally , My father has done no crime , And having a noncriminal working father detained for no such reason is just injustice , We need help from the community to help us get signatures so we can bring my father back home , thank you
