DNA testing plays an important part in completing the immigration process of family members. It helps establish a biological relationship between a petitioner and beneficiary, especially when evidence like birth certificates is missing or considered insufficient to support the application. These tests have to be carried out in an accredited and recognized lab and include paternity tests, maternity tests, siblingship tests and grandparentage tests.
Though there are some DNA tests kit providers on the internet, it’s not worth using them for DNA immigration testing as they are not recognized or approved by Immigration services and Embassies.
1. The lab has to be an accredited lab. It has to send sample collection kits and its clear collection instructions to the US embassy or any embassy approved physician practicing in the foreign country. Consequently, the testing laboratory has to directly coordinate with the US embassy and send a clear explanation of results once the test is complete.
2. The testing process should follow the chain of custody procedure wherein a neutral party collects the DNA samples after verifying the tested individuals’ identities through their IDs, photos and thumbprints.
3. The samples have to be securely and tamper-sealed packed at the collection site and should be carefully inspected for signs of tampering on arrival at the lab.
The preferred method to collect samples for an immigration DNA test is buccal swabbing. This involves using a swab to rub gently around the inside of your mouth to collect cheek cell samples. It is both painless and easy to perform. Moreover the fact that buccal swabbing is easy and cheap to ship makes it practical to use in immigration cases with far-away countries.
Wait for results
It usually takes 5-10 days to obtain DNA immigration testing results; including time spent for collecting and sending the samples back to the lab. Results of paternity tests are obtained much faster than tests for other relationships.
The results include the most likely relationship between the people tested and include statistics to prove this. Testing of closest relatives give the most conclusive results. In fact, a paternity test should establish a relationship of 99.5% or more to be considered valid proof of paternity.
