Legal Immigration DNA Test:
DNA testing uses scientific techniques to determine a person’s identity. This is usually done by analysing blood samples or cotton swab samples taken from cells on the inside of the cheek. Thus, a court may order DNA testing if a person’s identity needs to be established. DNA testing can also be used to determine a blood-relationship between two persons by comparing their samples. It is commonly used in paternity determinations, where the court needs to conclude which person is the father of a child.
When is the Legal Immigration DNA Test taken:
If a person is petitioning a blood relative (such as a sibling or child), an immigration judge may order DNA testing for both persons to establish that the two parties are related. Again, blood relationships are usually established through birth certificates.
However, it sometimes happens that a birth certificate was lost or destroyed, or is somehow inaccurate. If this is the case, DNA testing can be a last resort for persons wishing to petition their loved ones through the immigration system. The results from the DNA test can be used as evidence to show that two people are related to the purposes of immigration petitioning. The most common sample type is a buccal swab. This sample is collected using a cotton swab that is gently rubbed on the inside of your cheek. Blood samples are also acceptable.
