Less than 400 immigrants marched Saturday hoping to highlight a far-reaching immigration policy that allows undocumented workers to keep their families intact and bolster the American economy.

The participants carried banners and signs, along with U.S. and Mexican flags, in the march from Immaculate Conception Catholic Church in Houston to a local park.

A smaller group of around 20 counter protesters gathered near the rally chanting “USA, USA” and holding banners proclaiming “Texas is not a Mexican colony” and “Employers of illegals…traitors to America!”

50 Police officers, some on horseback stood between the counter-protesters and the rally to keep order.
