On International Migrants Day we celebrate our presence and elevate all that we bring to the societies that welcome us and to our countries of origin. The pillars on which U.S. society is built, for example, are the dreams and aspirations of migrants who come in search of security, dignity and opportunity. To fight for the well-being and integration of migrants in the United States is to fight for the future of one in four children born in this country. Migrants are an essential part of my community. Each one is like a piece of the puzzle that shapes our beautiful and diverse nation.
