Accurate Immigration DNA Testing Services in Kolkata for Sponsored Immigration

Many residents from Kolkata have family ties with their other members living abroad. Those members living abroad sometimes sponsor the visas of their family members living in India. When the primary visa documents fail to establish the sponsor-applicant’s biological link, the embassy may request a DNA test report for further validation.

For this reason, immigration DNA tests in Kolkata help applicants to strongly prove their family ties with their sponsor. A DNA test provides concrete evidence of a biological relationship, which is even accepted officially by the international embassies. 

Reasons Why Embassies Suspect a Visa Application

Immigration authorities can suspect a visa application for various reasons. But some of the most common reasons include: 

  • Prior history of visa rejection

  • Despite the biological relationship, the sponsor and the applicant have different surnames

  • The photographs of the applicant on the passport and visa application do not match

  • Missing or incomplete documents

Types of Family Connection Involved

DNA tests involve the following family links for the diverse needs of applicants:

  1. Paternity - for confirming the father-child genetic relationship.

  2. Maternity - to verify the mother-child biological link. 

  3. Siblingship - this validates the genetic link between siblings.

  4. Grandparentage - this test confirms the family ties between a grandparent and a grandchild.

  5. Avuncular - the family connection of an uncle/aunt with their niece/nephew is often confirmed using this test. 

Understanding the Immigration DNA Testing Procedure

DNA tests in Kolkata and all other cities in India are performed using the following straightforward steps: 

  1. DNA Sample Collection

DNA samples from the sponsor and the applicant are collected by a lab expert using a cheek swab method. The cotton swab is rubbed against the inside of the cheek walls to obtain the epithelial cells. It’s a safe, painless, and non-invasive procedure for individuals of all ages. 

If the sponsor and the applicant are living in different countries at the time of testing, the same lab coordinates the test accordingly. 

  1. Lab Analysis of the Samples

The collected samples are then securely sealed to prevent tampering and contamination and sent to a lab for further examination. The experts in the lab analyze and compare the DNA samples to find the potential genetic match between the tested individuals. 

  1. The Final Report

A final report is generated after completing the analysis of the DNA samples. The report clearly states the results of the tests. This report is then confidentially sent to the address of the tested party. 

Chain of Custody Procedure in Immigration DNA Tests

In some special cases, the embassy may demand a DNA testing procedure under a strict chain of custody procedure. In this process, the samples from the sponsor and applicant are collected in the presence of an embassy official. 

Until the samples are securely sealed in a tamper-proof package, the official continues to monitor the process. Moreover, the final report of this test is directly sent to the embassy that requested the test. In this case, the final report isn’t sent to the tested party’s address. 

This procedure includes additional costs and excessive time consumption. For this reason, it’s always recommended to submit a DNA test report along with the primary documents. This improves the authenticity and legitimacy of a visa application.
