In general, a person cannot be prevented from working in another state simply because they belong to a particular state within the United States. This is based on the Privileges and Immunities Clause of the U.S. Constitution, which prevents states from discriminating against citizens of other states in favor of their own.

However, there can be some exceptions or conditions, such as:

• Licensing Requirements: Certain professions (e.g., law, medicine, cosmetology) require state-specific licenses. Sameer would need to meet the licensing requirements of the state where he wants to work. U.S. Department of Labor - Licensing
• State Residency Requirements for State Jobs: Some state government jobs may require state residency. These requirements are usually permissible.
• Legitimate State Interests: There might be other very specific situations where a state could justify restrictions, but these would be rare and subject to legal scrutiny.

Therefore, unless Sameer's profession requires a state-specific license that he doesn't possess, or the job he's seeking has a legitimate residency requirement, he should generally be free to work in another state regardless of which state he is from.
