Trusted DNA Testing Services in Bengaluru for Family Reunification Purposes
Reuniting with family members abroad often requires more than just paperwork. When birth certificates are missing or documents seem questionable, embassies ask for reliable proof of the sponsor-applicant’s biological relationship.
In some cases, the traditional paperwork isn't enough to satisfy immigration authorities. As a result, for the residents of Karnataka, the Immigration DNA tests in Bengaluru offer reliable evidence of family connections to speed up the sponsored visa application process.
Situations Where a DNA Test Becomes Mandatory
The common suspicions due to which embassies may ask for a DNA test report:
History of sponsored visa rejection
Missing or incomplete documents
Photograph mismatch on the visa application and the passport
The sponsor and the applicant have different surnames
Such situations can raise doubts in immigration officers, leading to a request for a DNA test for further clarification.
Types of Relationships Verified Using Immigration DNA Tests
There are several types of family relationships verified using DNA tests in Bengaluru and other cities for immigration purposes.
Paternity - It’s used to confirm the father-child biological relationship in an immigration case.
Maternity - This test utilizes the mother's and child’s DNA samples to determine their genetic link.
Siblingship - The embassy often asks for a DNA test report to verify the genetic relationship between two alleged siblings involved in a sponsored immigration case.
Grandparentage - A grandparent and a grandchild’s family relationship in a sponsored visa can be verified with a DNA test.
Avuncular - In some cases, an uncle or an aunt living abroad sponsors the visa of their niece/nephew. Such family ties can also be confirmed with a DNA testing procedure.
How Does a DNA Test Confirm the Biological Relationship with Certainty?
An individual inherits 50% of their DNA from their mother and the other 50% from their father. Such inherited DNA also contains unique DNA markers.
A DNA marker is a set of unique code in a DNA that cannot be similar in two people unless they’re genetically related. During the examination of two or more DNA samples, experts look only for those DNA markers.
If the markers are identical, a biological relationship is established with certainty. Otherwise, it’s rejected firmly.
The Procedure of Immigration DNA Test
An immigration DNA test in Bengaluru and other cities is performed using the following simple steps:
Sample Collection
The samples of the sponsor and the applicant are collected by a lab expert. A cheek/buccal swab method is utilized to obtain the DNA sample from the inside of the cheek walls. It’s a painless, safe, and non-invasive procedure.
Additionally, if the sponsor and the applicant are living in different countries at the time of the test, the same lab coordinates the test accordingly.
Lab Analysis
The samples are later examined in the lab by experts to find a potential DNA match. For this procedure, they look for the unique DNA markers.
The Final Report
After finishing the analysis, a final report is generated, stating the results of the genetic relationship. This report is later sent to the tested party to attach to their sponsored visa documents.
