Immigration Testing

Reliable & Accredited Immigration DNA Testing Services

At Guardian Testing Solutions (GTS), we provide fast, accurate, and USCIS-approved DNA testing for immigration purposes. Whether you are petitioning for a family member, applying for citizenship, or seeking refugee status, our AABB-accredited testing ensures legally recognized results for your immigration case.
When documentation is insufficient, DNA testing serves as scientific proof of a biological relationship between petitioners and beneficiaries. We work directly with USCIS, U.S. embassies, and consulates to ensure a smooth testing process.

Who Needs Immigration DNA Testing?

✔ Family-Based Visa Applicants – Proving biological relationships for family reunification.

✔ Citizenship Applications – Confirming parent-child relationships for U.S. citizenship claims.

✔ Refugees & Asylum Seekers – Verifying family ties for legal immigration processing.

✔ Consular Processing Cases – When a U.S. embassy or consulate requires genetic proof.

If a U.S. immigration authority has recommended DNA testing, Guardian Testing Solutions can guide you through the process with ease and efficiency.
