DNA Testing Cost for Immigrants

The DNA testing cost is of concern for people who need to visit different places around the globe, especially when he is claiming himself as a relative of a US citizen and sponsored by him while entering The USA.

Generally a DNA test for the immigration purpose is done for verifying the passports, citizenship and immigration clearance for international travellers, students, businessmen etc. Immigration officers frequently request a DNA test report to confirm biological relationships with a US citizen while considering immigration visa.

Common DNA Testing Cost Questions

The common DNA tests asked for are paternity or standard paternity test and sibling relationships test. Hence DNA testing cost for immigration varies according to the type of test being conducted for a given purpose. When the applicant receives the request for DNA test, their DNA samples are collected, tested and the results are compared with that of their relatives which confirms their genealogy. The DNA samples are collected within a week using the DNA collection kit.

To initiate such a test the applicant must submit the order issues by the immigration official to the testing lab. The letter must contain the concerned person’s name along with their immigration case number. Attend the sample collection appointment, the samples of the relatives residing in any corner of the world, mentioned in the letter, are collected within 4-6 weeks.

DNA Testing Cost Affected by Location

A DNA testing cost will be higher if the samples need to be collected from far off places. The samples are also sent to the concerned offices to perform the testing. These samples will be received through proper chain of custody to initiate the testing process. The result is obtained within 5-7 business days. And the concerned person has to submit the documents to the immigration authority within specified time via mail.

The DNA testing cost varies on the type of the method involved in the process of the DNA extraction and testing. The test mainly performed is the standard paternity tests to find out the ancestral information. This is done by testing the y chromosomes. The short tandem repeats or in short STRs that are present on the Y chromosome are tested. The STR segments that are examined are referred to as the genetic markers. These are repetitive units that vary from person to person.

But due to the concept of polymorphism there will be a change in the single nucleotide in the relative DNS sequence. This will help them in identifying the history of the person’s genetic tree. This polymorphism is called as single nucleotide polymorphism (SNP). Despite a change in the DNA sequence the mutation rate of the SNP will not very much.

DNA Testing Cost Range

There are different ranges of the DNA testing costs based on technologies and this testing can also be done based on the mitochondrial analysis. This is done because of the replication of more number of the STRs when the sample gets degraded. The [mtDNA] mitochondrial DNA is maternally inherited which will help in directly identifying the maternal relatives. This gives a much more clear idea of the historical maternal ancestry. These tests are useful in the missing cases and this mtDNA can be found in hair shafts, bones and teeth.

All the samples of the DNA are stored in the DNA databases for future references by the government which might be useful to identify the records of the criminals.

The DNA testing cost for immigration tests cost 350$ – 400$ and it takes 10-15 days to get the results.
