When a person interested in a TN visa reviews a job offer, it is essential to verify that the company is legitimate and compliant with legal requirements in the United States. One way to attest to the credibility and existence of a company is through the presentation of official documents that prove its incorporation and regularity.

Among the most common documents that can be useful are:
• Certificate of incorporation or official registration – issued by the Secretary of State of the state where the company was registered;
• Business licenses and permits – demonstrating that the company holds the necessary licenses to operate legally;
• Employer Identification Number (EIN) – provided by the IRS (Internal Revenue Service), which confirms the existence of an active tax entity;
• Financial documents, such as tax returns, recent bank statements, or financial statements – evidencing the company’s financial health and commercial activity;
• Contracts, invoices, or official letters showing interactions with other business partners or clients – which may serve as proof that the activity is continuous and legitimate.

It is important to emphasize that when analyzing a company”s documentation, you should always follow the United States immigration laws and be alert to warning signs. There are many marketing campaigns and suspicious offers out there, and, unfortunately, scams can happen. Whenever possible, it is worth seeking support from professionals specialized in immigration and investigating the public records of the state where the company is registered to confirm the information.

Remember also that this information is for informational purposes only and does not replace personalized consultation with a specialist in the field. Be sure to conduct thorough and cautious research to ensure that all presented documentation is valid and up to date according to the country”s regulations.
