A DNA paternity test may be required for a child or father living in a different country to be allowed to immigrate to the United States. The United States State Department often requires this verification before allowing a United States citizen to sponsor an immigrant. This may be required regardless of country of origin for the immigrant.
Immigration for undocumented students, may require a DNA test if US citizen parents did not submit correct paperwork.
