for Immigration & Asylum Cases

Immigration and asylum cases often involve deeply personal stories, complex legal requirements, and situations where credibility is critical. At Spectrum Polygraph Services, we provide confidential, professional, and bilingual polygraph testing (English & Spanish) to help individuals, families, and attorneys strengthen immigration cases with reliable credibility support.

Whether you are facing a USCIS interview, an asylum hearing, or an adjustment of status application, our immigration-focused lie detector exams are tailored to verify truthfulness in sensitive situations such as Quilantan entries, marriage fraud allegations, VAWA petitions, asylum claims, and more.

Our goal is not to replace documentation, but to support your case when evidence is limited, lost, or questioned.

When Immigration Polygraph Testing Can Help

Polygraph testing may play a key role in a variety of immigration and asylum situations:

  • Supporting testimony when documents are unavailable or destroyed

  • Verifying the legitimacy of marriage or family-based petitions

  • Strengthening claims of persecution, abuse, or trafficking

  • Confirming criminal history disclosures or clearing misunderstandings

  • Providing credible evidence in asylum or VAWA petitions

  • Assisting attorneys with pre-interview case preparation

Each case is unique, and our exams are customized to reflect the exact legal and personal concerns raised by USCIS, ICE, or immigration courts.

Quilantan Entry Verification
Under the Quilantan principle, individuals may apply for status adjustment even if they entered the U.S. without inspection, provided the entry was otherwise lawful. A polygraph exam can help confirm truthful accounts of entry circumstances when documentation or witness testimony is unavailable.

Adjustment of Status
For applicants seeking permanent residency, USCIS may question the truthfulness of personal statements or relationship claims. Polygraph testing can help establish credibility in the adjustment process, offering attorneys an additional tool to present trustworthy evidence.

Human Trafficking Cases (T-Visas)
Victims of trafficking often face challenges proving coercion, exploitation, or abuse. Our polygraph exams can help confirm truthful accounts, adding weight to T-Visa applications when official records are incomplete or unavailable.

Persecution-Based Claims

Applicants may face credibility challenges when recounting persecution from government or social groups. Polygraph testing can support consistency in personal testimony, adding credibility during asylum hearings.

Legitimacy of Purpose of Entry

If the purpose of U.S. entry is questioned (family reunification, employment, education, or asylum), polygraph exams can confirm genuine intentions, reducing suspicion of fraudulent or misrepresented entry.

Lost or Missing Document Support

When vital immigration records are missing, destroyed, or unobtainable, polygraph testing offers an alternative method of credibility validation. This is particularly useful in asylum cases from countries with unstable governments or limited record-keeping.

Marriage Fraud Investigations
USCIS strictly investigates potential fraudulent marriages. A polygraph exam can demonstrate whether the marriage was entered into in good faith, providing critical support against allegations of fraud in both removal proceedings and adjustment cases.

VAWA (Violence Against Women Act) Petitions
For individuals applying under VAWA due to abuse from a U.S. citizen or permanent resident spouse, polygraph testing can help confirm abuse accounts, especially in cases where victims lack police reports, restraining orders, or medical documentation.

Asylum Claims
Asylum seekers must prove past persecution or fear of future harm based on religion, nationality, politics, or social group. Polygraph testing can reinforce testimony, showing credibility in claims of torture, threats, or persecution where supporting evidence is scarce.

Criminal History Verification
Polygraph exams can confirm whether an applicant has truthfully disclosed criminal history, a common area of concern in background checks. A truthful exam can strengthen good moral character arguments in USCIS cases.
