Due to the chain-of-custody process, the legal DNA test is the only accepted in court. One of the most basic reasons for ordering legal tests is for immigration purposes. And, there are some key differences between immigration and all other legal usages. But apart from that, both tests are for these reasons:
Obtaining paternity advantages
Life/ healthcare coverage
Social Security
Welfare Benefits
Succession
Outside of marriage
Protecting a father’s rights
Parental rights and custody rights
The individuals undergoing DNA testing cannot demand the test unless they have received the order from USCIS or Consulate office. If a petitioner desires a DNA immigration test before obtaining the official document from USCIS, it can face rejection.
Only AABB-accredited labs can arrange appointments in the United States or overseas. They have locations for shipping DNA collection kits to US Embassy and Foreign Offices all around the world. The final results go straight to the immigration office rather than the petitioner.
The USCIS cannot legally compel a petitioner seeking immigration to take a DNA test; they can only recommend it. When paternity seems suspicious, a court can order legal DNA testing as part of a trial for legal proceedings to determine paternity. And to check whether a person can have the benefits.
