Two people with the same job, family relationship, and travel plan can face different U.S. immigration procedures because their passports are issued by different countries. Nationality can affect eligibility, fees, document rules, and how a case is processed.
Visa Waiver eligibility
The Visa Waiver Program allows eligible citizens and nationals of participating countries to seek admission for tourism or business for up to 90 days without first obtaining a visitor visa, subject to ESTA and other requirements. The State Department’s Visa Waiver page lists the program and its limits. A person who holds more than one nationality may need to use the passport required by the program and disclose other citizenships.
Reciprocity rules
For many Nonimmigrant visaA visa for a temporary stay for a specific purpose, such as study, tourism, or employment, for example F-1, B-2 or H-1B.See it in the glossary categories, the State Department’s country-specific reciprocity tables show whether an issuance fee applies, how many entries are permitted, and how long a visa may be valid. These terms can differ by nationality even when the visa category is the same.
Civil documents are country-specific
Birth certificates, marriage records, police certificates, and court documents are issued under local systems. The State Department’s civil-document guidance directs applicants to the country-specific document finder. The correct document may depend on where an event occurred, not only where the applicant lives now.
Nationality is not the same as residence
An applicant may lawfully apply in a country of residence, but the issuing post and document requirements can depend on both residence and nationality. A passport also must be valid for travel and may need blank pages or a minimum period of validity under the relevant process.
Country-specific restrictions can change
Presidential proclamationA formal statement from the President addressed to the public. In immigration, proclamations are often issued under INA 212(f), which lets the President suspend or restrict the entry of noncitizens when the President finds their entry would be detrimental to the interests of the United States. The Supreme Court read that authority broadly in Trump v. Hawaii (2018), though courts have said it cannot override other parts of the INA.See it in the glossary, security rules, or changes to consular operations can affect nationals of particular countries. Check the current State Department notices and the website of the embassy or consulate handling the case before relying on older advice.
What to do before filing
List every nationality and passport, confirm which passport you will use, review the applicable reciprocity table, and obtain civil documents from the correct issuing authority. If names or dates differ across passports and records, explain the difference with official evidence.
