Many professionals working in the United States on H-1B status travel to Canada for conferences, business meetings, short-term assignments, or personal reasons. However, even a single DUI conviction — whether recent or many years old — can create unexpected immigration problems at the Canadian border.

Importantly, a DUI that does not affect U.S. immigration status may still render a traveler criminally inadmissible to Canada under Canada’s immigration laws.

Understanding how Canada treats impaired driving offenses is critical before making travel plans.

Why Canada Treats DUI Offenses Differently

Under Canada’s Immigration and Refugee Protection Act (IRPA), certain impaired driving offenses are treated as serious criminal matters. A DUI that may be classified as a misdemeanor in the United States can still trigger inadmissibility to Canada.

Canadian officers assess:

• How the offense would be treated under Canadian law,

• The maximum possible penalty under Canadian law,

• Whether all sentencing requirements were completed.

This applies regardless of:

• Whether it was a first offense,

• How long ago it occurred,

• Whether probation or fines were completed,

• Whether U.S. immigration status remains valid.

The analysis focuses on Canadian equivalency — not U.S. classification.

How This Affects H-1B Holders

H-1B holders may face issues when:

• Flying to Canada for short business trips,

• Attending conferences or client meetings,

• Entering Canada by land or air,

• Transiting through a Canadian airport.

Canadian border authorities have access to shared criminal information databases and may identify a DUI even if it is not disclosed proactively.

In many cases, professionals discover the issue only at the airport or land border, leading to immediate travel disruption.

What Can Happen at the Canadian Border?

If a prior DUI is identified, a border officer may:

• Deny entry to Canada,

• Cancel travel plans immediately,

• Conduct detailed questioning,

• Issue a record of refusal,

• Flag the traveler for future scrutiny.

Unlike U.S. immigration processes, Canadian officers exercise broad discretionary authority at the port of entry.

Does Time Since the DUI Matter?

Time can matter — but it does not automatically resolve inadmissibility.

Eligibility depends on:

• The date of conviction,

• The sentence imposed,

• When all penalties were fully completed (including probation, fines, and license conditions),

• The Canadian equivalent offense classification.

Some individuals may eventually qualify for permanent relief, while others require a temporary solution before travel.

Assumptions about “old” DUIs no longer being relevant can lead to unexpected refusal.

Options for H-1B Holders With a DUI

Depending on the circumstances, options may include:

1. Temporary Resident Permit (TRP)

A discretionary, short-term authorization allowing entry despite inadmissibility for a specific purpose.

2. Criminal Rehabilitation

A permanent solution that removes criminal inadmissibility once approved.

3. Advance Legal Assessment

A formal review before travel to determine admissibility risk and appropriate strategy.

The correct approach depends on timing, urgency of travel, and the nature of the offense.

Why Planning Ahead Is Essential

Attempting to resolve a DUI issue at the border without preparation often results in refusal.

Advance planning can help prevent:

• Denied boarding,

• Missed business obligations,

• Cancelled conferences or contracts,

• Long-term border flags that complicate future travel.

Cross-border professionals should address admissibility before booking travel.

Final Takeaway

Frequently Asked Questions: H-1B Holders, DUI, and Travel to Canada

Does a DUI affect my H-1B status in the United States?
In most cases, a single DUI does not automatically cancel H-1B status. However, it can complicate international travel.

If my DUI was many years ago, can I still be denied entry to Canada?
Yes. Canada does not automatically overlook older DUIs. Eligibility depends on Canadian law equivalency and sentencing completion.

Will Canadian border officers know about my DUI if I don’t mention it?
Often, yes. Canadian authorities may access shared law enforcement databases.

Can I just explain my DUI at the border?
In most cases, explanation alone is insufficient if you are legally inadmissible.

What is a Temporary Resident Permit (TRP)?
A TRP allows temporary entry to Canada despite inadmissibility for a limited purpose and duration.

What is Criminal Rehabilitation?
Criminal Rehabilitation permanently removes certain criminal inadmissibility once approved.

Which option is better: TRP or Criminal Rehabilitation?
A TRP is short-term and discretionary. Criminal Rehabilitation is permanent but requires eligibility and longer processing.

Should I apply before booking travel?
Yes. Addressing admissibility in advance reduces the risk of refusal and future complications.

Can Visaserve Immigration Law P.C. review my case before travel?
Yes. We provide admissibility assessments and strategic guidance before cross-border travel.
