Opening Doors International Services, Inc. was established in April 2003 in response to an immigration crisis that affected a member of the congregation of Trinity Presbyterian Church in Denton. The congregation responded to the needs of one of its members with great compassion. At the time, no legal assistance for immigrants existed in Denton County. Church volunteers underwent training in immigration law and procedures, made possible by a grant received from The Women's Birthday Fund and from the Trinity Presbyterian Church.

ODIS, Inc. initially began as part of Trinity Presbyterian Church. In 2009, ODIS, Inc. incorporated to become its own separate legal entity and obtained 501(c)(3) non-profit status in its own name. So far, ODIS, Inc. has assisted over 800 clients from 86 countries and proudly boasts a 100% success rate in all petitions and applications filed with the U.S. Citizenship and Immigration Service (USCIS).

Staff members who are accredited by the U.S. Department of Justice’s Board of Immigration Appeals provide immigration legal advice to clients and prepare cases for submission to USCIS. Volunteers assist with myriad other tasks necessary to our daily operations. In addition to providing legal services directly to our clients, we also participate in outreach to the local community in order to raise awareness about our services for immigrants and their families, and for immigrant victims of domestic violence and other crimes.
