If you are planning to join your loved ones living abroad, proving your biological connection is a key part of the process. Immigration authorities usually verify such family links using primary documents such as birth certificates or other documents. But in some cases, such documents do not hold that much authenticity.
This is where choosing a professional provider for immigration DNA tests in Guwahati can make your visa application approval much smoother. DNA tests provide the undeniable proof that international embassies require to process your request with confidence.
The Need for Immigration DNA Tests in Guwahati
While it is not always mandatory for everyone, it becomes essential if the documents you have submitted are not enough to satisfy the immigration officers. Embassies of countries like the UK, the US, Canada, and Australia have strict protocols to prevent fraudulent claims.
Common Reasons for a DNA Test Request:
- Missing Official Records: In case of missing or incomplete documents, a DNA test serves as the only reliable proof of family relationship.
- Inconsistent Information: If there are differences in the names or dates on your paperwork, the embassy may ask for a biological test to clear up any confusion.
- Embassy Doubts: Immigration officers may sometimes doubt the authenticity of your submitted papers and will suggest a DNA test to confirm the truth.
Types of Relationships in Family Reunification
Depending on your specific visa needs, you can use DNA tests in Guwahati to confirm various types of family bonds.
- Paternity Testing: This verifies the biological link between a father and a child.
- Maternity Testing: This confirms the genetic connection between a mother and her child.
- Siblingship Testing: If parents are not available, this test can show if two individuals share one or both parents.
- Grandparentage Testing: This establishes the biological link between a grandparent and a grandchild.
- Avuncular Testing: This verifies the relationship between an uncle or aunt and their niece or nephew.
The Procedure of DNA Testing
It involves a few straightforward steps:
Step 1: Booking an Appointment – Initially, the sponsor and applicant schedule an appointment at a lab to have their DNA samples collected. If both individuals are living in different countries at the time of the test, the same lab coordinates the test accordingly.
Step 2: Sample Collection – A lab expert collects the DNA samples from the sponsor and the applicant using a cheek swab method. A cotton swab is rubbed against the inside of the cheek walls to collect epithelial cells. It is a safe and non-invasive procedure for individuals of all ages.
Step 3: Lab Analysis – After the samples are collected, they’re securely sealed to avoid tampering and contamination. Then, they’re sent to a lab, where the lab experts analyze and compare them to find the potential genetic match.
Step 6: The Final Report – After finishing the analysis, the lab experts generate a final report, which states whether or not the biological relationship exists. This report is then confidentially sent to the tested party’s address.
However, in the case of the Chain of Custody procedure, the report isn’t sent to the tested party. Instead, it’s sent to the embassy that requested the test. It’s to maintain the privacy and confidentiality of the report.
Moreover, in a chain of custody procedure, the DNA samples are collected under the supervision of an embassy official. Until the samples are securely sealed, the official continues to monitor the process to ensure the samples aren’t contaminated or tampered with.
The Cost of Immigration DNA Tests in Guwahati
The cost of your test can vary based on several factors, including the number of people being tested and the country you are applying to. Because immigration tests require a strict legal process and specialized handling, they usually cost more than standard tests done for personal knowledge.
Factors Influencing the DNA Tests Cost
Number of People in the Test – The more people in the test, the higher the cost of a DNA test. For instance, in a DNA test, only one sponsor and an applicant are present. But if an additional applicant is included, it’ll significantly increase the cost of a DNA test.
