DNA testing is the most modern and accurate tool for establishing parentage at the moment. The paternity DNA test aids in the establishment of a father-child link. Before, a birth certificate was enough to prove legitimacy between a father and a child. But, in the pursuit of accuracy in DNA test results for authorities, people use DNA testing to verify paternity.
The DNA you get from your parents is deoxyribonucleic acid or DNA. A DNA paternity test determines if a guy is the child’s biological father by using DNA from a cheek swab.
In rare cases, an immigration officer may need the applicant to give the results of a paternity DNA. This is to test to confirm a biological relationship stated in their application.
If the father is the sponsor they need a paternity report, you will need a sample from the mother as well. Thus, a maternity report is not necessary. Unless authorities suspect the mother of not being the biological parent.
There are two methods for determining paternity:
Blood tests: At a medical office, the father and child provide blood samples. Then experts send the samples to a lab for examination by the facility.
Buccal swab: In this method a you swab the inside of your mouth for buccal cells. These cotton swabs then provide the sample needed for paternity DNA test.
