Hopefully you won't need this any time soon, but I think it's important to have a reasonably accurate set of resources available and easy to find, just in case. I strongly recommend at least giving it at least a passing look now to make sure you know if there's resources in your area. Don't wait until the last minute.
Unfortunately, as most of us know, your resources for getting help to contest a deportation are still relatively slim, especially if you don't live on the coasts. But it's 24 pages that can at least give you a good heads up of what to expect. Via SEARAC:
"People facing deportation to Cambodia, Laos, and Vietnam often arrived in the United States as refugee children, growing up in failing schools and unsafe neighborhoods plagued by violence and intergenerational poverty. Because of these unique circumstances, SEARAC, together with the Immigrant Justice Clinic of the American University Williams College of Law, created a deportation guide to help non-citizens from Cambodian, Hmong, Laotian, and Vietnamese American communities (together with their advocates) navigate our country's complex detention and deportation systems."
