The United States is enforcing a series of tightened document and visa requirements that are altering the conditions of entry and stay for both its own citizens and foreign nationals. US Customs and Border Protection (CBP) now routinely bars travellers holding passports with severe damage, stains or torn visa pages, and reminds visitors that many countries and airlines require at least six months’ remaining validity beyond the travel date. The Transportation Security Administration (TSA) has begun charging a $45 “ConfirmID Fee” for domestic passengers who arrive at airport checkpoints without a REAL ID-compliant licence or alternative federal document, a measure that took effect in February 2026 after the full implementation of the REAL ID Act. Simultaneously, CBP has moved to automatically revoke the visas of foreign commercial drivers who use business or tourist visas to perform activities the agency classifies as unauthorised employment, with California, Texas and Florida border sectors identified as enforcement hotspots.

The cost of acquiring US citizenship is set to rise sharply under a Department of Homeland Security (DHS) proposal that would increase the naturalisation application fee (Form N-400) by 75 per cent for paper filings and 80 per cent online, while eliminating fee waivers and reductions for lower-income applicants. Viewed from New Delhi, the change would disproportionately affect Indian nationals, who constituted the second-largest group of new US citizens in fiscal year 2024. DHS argues the increases are necessary to recover the full cost of adjudication and expanded vetting. A separate proposed regulation, cleared by the White House Office of Management and Budget, would replace the decades-old “duration of status” framework for international students with a fixed four-year admission cap, requiring those in longer programmes—including many Indian PhD and research students—to seek formal extensions from US Citizenship and Immigration Services. Higher education associations in Washington have warned that the shift would inject uncertainty and administrative burden into academic planning.

The enforcement wave extends to specific border-crossing populations. CBP has cautioned Mexican nationals that presenting the Border Crossing Card (BCC) outside the permitted border zones—25 to 75 miles depending on the state—can trigger immediate deportation if the holder has an outstanding detention order. Meanwhile, the US mission in Nigeria publicly urged visa holders to honour authorised stay periods, warning that violations could jeopardise future travel. In a contrasting flexibility, Canadian citizens travelling by land or sea retain the option of using alternative identity documents and are generally exempt from visa requirements for tourist visits of up to six months, though certain activities still require a visa. Outside the US, Spain’s government has similarly reminded travellers that passports must have at least three months’ validity beyond the planned departure from the Schengen area, reflecting a broader international tightening of document enforcement.

These measures sit within a wider recalibration of US immigration policy under the current administration. The naturalisation fee proposal is open for public comment for 60 days before a final rule is issued. The student visa regulation is expected to be published in the Federal Register with an implementation window of 30 to 60 days thereafter. The REAL ID enforcement and the ConfirmID fee are already operational. In parallel, a small but notable number of Americans with Canadian ancestry are quietly pursuing Canadian citizenship by descent as a personal hedge against domestic uncertainty, according to immigration lawyers cited in North American media. The cumulative effect, as seen from capitals in Latin America, South Asia and Europe, is a more demanding and less predictable US entry environment.
