Immigration DNA Testing in Rancho Cucamonga

Local Petitioner Collection for Family-Based Immigration Visas

Fastest Labs of Rancho Cucamonga is the local collection point for immigration DNA testing in Rancho Cucamonga, serving petitioners and their families across San Bernardino County, including those in Fontana and Ontario. When a visa applicant can’t provide sufficient documentary evidence of a biological relationship with their U.S. relative, USCIS or a U.S. embassy may suggest DNA testing. If that path is chosen, federal agencies require the test to be conducted by an American Association of Blood Banks (AABB) accredited laboratory. We work exclusively with AABB accredited labs for every immigration case.

Our role is straightforward: we collect the petitioner’s cheek swab sample here in Rancho Cucamonga, send it to our AABB accredited laboratory partner, and the visa applicant has their sample collected separately at a U.S. embassy or consulate. Most clients are seen within minutes of arriving.

How Immigration DNA Testing Works

The petitioner and the visa applicant don’t need to be in the same location. Collection happens at two separate sites, and the AABB accredited laboratory connects both samples to produce the final result.

The Petitioner’s Appointment in Rancho Cucamonga

The petitioner visits Fastest Labs of Rancho Cucamonga, where a certified collector takes a cheek swab sample. That sample is sent directly to our AABB accredited laboratory partner for analysis. Bring a government-issued photo ID to this appointment.

The Visa Applicant’s Appointment Overseas

The visa applicant is directed to have their cheek swab collected at a U.S. embassy or consulate, where embassy officials witness the collection to support the integrity of the process. The visa applicant must bring a passport, a photo, and a receipt from the panel physician showing payment for the DNA collection. Without that receipt, the appointment will need to be rescheduled. Scheduling at the embassy or consulate depends on that location’s availability and is outside our control.

Results & Next Steps

Once both samples are analyzed, results are made available so the visa applicant can take the next steps in the application process. DNA testing is voluntary when suggested by USCIS, but if you choose to proceed, AABB accreditation isn’t optional. Home DNA test kits don’t meet chain-of-custody requirements and won’t be accepted.

Relationship Types We Can Test

USCIS or the requesting embassy specifies which individuals need to be tested and what relationship must be verified. Immigration DNA testing can establish a range of biological relationships.

Testable relationships include:

Parent-child: Paternity or maternity testing to confirm a direct biological relationship between a parent and child
Grandparent: An option when a biological parent isn’t available to participate
Sibling: Used to verify a biological sibling relationship between a petitioner and visa applicant
Other relatives: Additional close biological relationships as specified in official correspondence from USCIS or the embassy

AABB Accreditation & What to Bring to Your Appointment

AABB accreditation means a laboratory has been assessed against comprehensive quality standards and follows validated procedures at every step, including maintaining a valid chain of custody from the moment the cheek swab is collected in Rancho Cucamonga through final result reporting. USCIS, U.S. passport agencies, and U.S. embassies accept DNA results only when the case is initiated by and reported directly from an AABB accredited laboratory. At Fastest Labs of Rancho Cucamonga, we work exclusively with fully AABB accredited and experienced laboratories for all immigration DNA testing services.

What to Bring

Required documents and helpful items for your Rancho Cucamonga collection appointment:

Government-issued photo ID: Required for all adult participants at the time of collection
USCIS or embassy correspondence: Any letters, case numbers, or written instructions you’ve received help our team align the collection with official case requirements
Payment receipt: If you’ve already paid for testing, bring the receipt, especially if the visa applicant will need it for their embassy appointment

A Few Things to Know Before You Arrive

Avoid food, gum, or smoking for a short period before your cheek swab appointment to improve sample quality. It’s also worth knowing that immigration DNA testing is typically suggested after a Request for Evidence or similar correspondence from USCIS. Results obtained independently before an official request may not be accepted, so confirm the timing with your immigration case before scheduling.
