Planning to join your family abroad is one of the most exciting steps. You gather a passport, along with other primary visa documents, to prove your family ties with your sponsor. But sometimes these documents alone aren’t enough to convince the immigration authorities. Therefore, they demand a more absolute proof, which is a DNA report. In such cases, an immigration DNA test in Mohali can help many Punjab-based applicants to strongly prove their family ties with their sponsors. A DNA report provides accurate information regarding the biological connections, which cannot be questioned. It can significantly help in a seamless family reunification when other documents fail.
Why Embassies May Ask for a DNA Report
Visa officers look closely at every detail before approving a sponsored application. They may ask for a DNA report when:
- Your surname is different from your sponsor's surname
- Your birth certificate is missing, damaged, or incomplete
- Photos on your passport and visa documents don't clearly match
- You have a history of a previous visa refusal
When these issues come up, a DNA report gives the embassy the clear answer it needs.
DNA Testing Process for Sponsored Immigration
A DNA testing process involves the following straightforward steps:
Step 1: You and your sponsor book an appointment at a lab, even if you live in different countries.
Step 2: A lab expert collects your sample using a soft cheek swab, which takes only a few seconds.
Step 3: Your sample is sealed and sent to the lab, where experts compare genetic markers between you and your sponsor.
Step 4: You receive a final report once the comparison is complete.
Chain of Custody Procedure in DNA Tests
In some cases, the embassy may demand a DNA test under a chain of custody procedure. During this test, an embassy official is present to monitor the whole sample collection process. Before collecting the samples, the official verifies the identities of the individuals involved in the DNA test. It’s to make sure that the right parties are present in the test.
The collected DNA samples are then securely sealed in front of the official. The DNA report of a chain of custody test is sent directly to the embassy that requested the test. In this case, the report isn’t sent to the tested party to maintain its privacy and integrity.
