The Differences Between Requesting an Appeal vs. a Waiver

When the Transportation Security Administration (TSA) issues a Preliminary Determination of Ineligibility—often in connection with a Transportation Worker Identification Credential (TWIC) or other security threat assessment—you are placed in a difficult position. This determination indicates that, based on the agency’s review of your criminal history, immigration status, or other security-related factors, you do not currently meet eligibility standards.

At that point, individuals are typically presented with two primary options: filing an appeal or requesting a waiver. Understanding the legal distinctions between these options—and the governing federal regulations—is critical to making the right decision.

The Legal Framework Behind TSA TWIC Determinations

TSA security threat assessments, including those for TWIC applicants, are governed primarily by Title 49 of the Code of Federal Regulations (CFR), particularly:

• 49 C.F.R. § 1572.103 – Disqualifying criminal offenses
• 49 C.F.R. § 1572.107 – Waivers
• 49 C.F.R. § 1572.141 – Appeals procedures

These regulations establish both the criteria for ineligibility and the procedural rights available to you. Under 49 C.F.R. § 1572.103, certain criminal offenses are categorized as either permanently disqualifying (e.g., espionage, terrorism, treason) or interim disqualifying (e.g., certain felonies within a defined time frame, typically 7 years since conviction or 5 years since release from incarceration). If TSA believes you fall within one of these categories, it issues a preliminary determination. However, that determination is not final. You have the right to challenge or mitigate it.

There are additional relevant laws and considerations that can apply to TSA TWIC preliminary determinations of ineligibility.First, you want to be mindful of the Administrative Procedure Act (APA) – 5 U.S.C. § 551 et seq. The APA governs how federal agencies make decisions and ensures that individuals are afforded due process. If TSA acts arbitrarily or fails to follow its own procedures, there may be grounds for further legal challenge under administrative law principles. Second, the Privacy Act of 1974 – 5 U.S.C. § 552a also applies to TSA TWIC cases since TSA relies on personal data and criminal history records. The Privacy Act provides individuals the right to (1) access records about themselves and (2) request correction of inaccurate information.

This can be particularly relevant in appeal cases involving incorrect background checks. Finally, general due process considerations apply. Although TWIC and similar credentials are not always considered a “right,” courts have recognized that denial can impact employment opportunities. As such, applicants are entitled to notice and an opportunity to respond, which is precisely what the appeal and waiver process provides.

What is the difference between an appeal and a waiver?

What Is an Appeal?

An appeal is appropriate when the issue is not the underlying conduct itself, but rather the accuracy or applicability of the information used by TSA. Under 49 C.F.R. § 1572.141, an individual may appeal a determination if they believe:

• The criminal record is incorrect or incomplete
• The record belongs to another person
• The offense does not meet the legal definition of a disqualifying crime
• The timing of the offense falls outside the disqualifying period.

In other words, an appeal is a fact-based challenge. Some examples of strong appeal grounds would include the following:

• A background check lists a conviction that was expunged, dismissed, or overturned
• TSA misclassified a misdemeanor as a felony
• The applicant shares a name and date of birth with another individual (identity error)
• The offense occurred beyond the 7-year or 5-year regulatory window.

In these cases, the applicant is not asking TSA for leniency—they are asserting that the agency made a legal or factual error. Working with a federal employment law attorney can help you supporting an effective appeal. A good attorney will help you present documentary evidence, such as certified court records, proof of disposition documents, and proof of identity (to resolve mistaken identity issues). TSA relies heavily on federal and state databases, so sometimes errors do occur. Appeals are often the fastest and most effective path when the issue is clearly incorrect data.

What Is a Waiver?

A waiver, governed by 49 C.F.R. § 1572.107, is fundamentally different. Here, the applicant does not dispute the disqualifying offense. Instead, they request that TSA exercise discretion and allow eligibility despite it. A waiver is essentially a case for second chances. Federal regulations explicitly allow TSA to consider a range of mitigating factors, including:

• The nature and seriousness of the offense
• How much time has passed since the conviction or release
• Evidence of rehabilitation
• Work history and stability
• Character references
• Whether the applicant poses a security threat.

Unlike an appeal, a waiver is subjective. TSA evaluates whether granting access credentials would still be consistent with national security. A Waiver May Be Appropriate when (1) a  felony conviction occurred many years ago, and the applicant has maintained steady employment since:

• The applicant has completed rehabilitation programs or demonstrated significant personal reform
• The offense was non-violent and unlikely to indicate a current security risk
• The applicant has strong community ties and references.

Notably, a waiver does not erase the disqualifying factor—it asks TSA to look beyond it which is why having a supportive federal employment law attorney on your side can help.

Can You File Both an Appeal and a Waiver?

Yes. In many cases, applicants may pursue both an appeal and a waiver simultaneously or sequentially. If there is uncertainty about the accuracy of records, an appeal may be filed first. Or, if the appeal fails or confirms the disqualifying offense, a waiver can then be pursued. This dual-track strategy can be particularly useful when the facts are complex or incomplete.

Strategic Considerations: Which Should You Choose?

he decision between an appeal and a waiver depends heavily on the specific facts of your case. Choose an Appeal if (1) you believe TSA made a mistake; (2) the record is factually inaccurate; and/or (3) the offense should not legally disqualify you.

You might choose a waiver if (1) the offense is accurate and actually disqualifying; (2) you have strong rehabilitation evidence; and/or (3) enough time has passed to show you a reduced risk.

Some individual may want to consider both an appeal and a waiver if there is uncertainty about the record or you want to preserve all possible avenues for approval. There are some common mistakes you will want to avoid during though. They include:

• Filing the wrong type of response. Submitting a waiver when the issue is actually a factual error can weaken your position.
• Insufficient documentation. Whether appealing or requesting a waiver, evidence is critical.
• Missing deadlines. TSA provides a limited window to respond to preliminary determinations.
• Failing to explain context. Particularly in waiver requests, simply listing facts is not enough—you must tell a compelling story of rehabilitation and reliability.

Why Legal Guidance Matters

The TSA process is highly technical and governed by federal regulations that can be difficult to interpret without experience. Small details—such as how an offense is categorized under 49 C.F.R. § 1572.103—can significantly impact the outcome. A federal employment law attorney can:

• Analyze whether the determination is legally correct
• Identify the strongest grounds for appeal or waiver
• Assemble supporting documentation
• Present a persuasive argument tailored to TSA’s criteria.

Final Thoughts

A TSA Preliminary Determination of Ineligibility is not the end of the road. Federal regulations provide clear mechanisms through appeals and waivers for individuals to challenge or overcome these determinations. The key is choosing the right strategy. An appeal focuses on correcting errors. A waiver focuses on demonstrating rehabilitation and trustworthiness. In some cases, both may be appropriate.

Facing an issue with your TSA TWIC can feel daunting and stressful but you don’t have to walk through the process alone. Carefully evaluating your situation in light of federal regulations can make all the difference in achieving a successful outcome.
