The Continuous Residence Clock

Can you spend six months with your parents in India without hurting a citizenship application? There is a statutory answer, it is precise, and it is almost never stated correctly — because two requirements run at once and they measure different things. A long absence can satisfy one and destroy the other. Both are worked below, in your browser.

Your travel

This page reads the five-year rule from the statute. The shorter period exists under separate provisions that were not read at source here — pick it and the page still does the arithmetic, but says so.

The rulebook, verified

Two clocks, not one: five years of residence AND half that in physical presence verified

The statute requires that the applicant has RESIDED CONTINUOUSLY, after lawful admission for permanent residence, for at least five years, AND during those five years has been PHYSICALLY PRESENT for periods totalling AT LEAST HALF of that time, AND has resided in the State or district of filing for at least three months. Continuous residence and physical presence are different tests measured differently. Somebody can hold uninterrupted residence and still fail the day count, and somebody can have plenty of days and still have broken continuity with one long trip.

8 U.S.C. §1427(a) primary source verified 2026-08-26

Six months to a year: continuity is broken UNLESS you can prove otherwise verified

An absence of more than six months but less than one year SHALL BREAK the continuity of residence — unless the applicant establishes that they did not in fact abandon their residence during the period. The default is against the traveller and the burden is on them to displace it. This is why the six-month mark is treated as a hard line in practice even though the statute makes it rebuttable: crossing it converts a non-question into something you have to argue.

8 U.S.C. §1427(b) primary source verified 2026-08-26

A year or more breaks it, and the exceptions are narrow verified

Absence for a continuous period of ONE YEAR OR MORE during the period for which continuous residence is required SHALL BREAK the continuity of residence, except in specified employment circumstances involving the United States government, recognised research institutions or certain international organisations. Unlike the six-month rule, this is not framed as something the applicant may rebut with evidence of intent — it either fits an exception or it breaks the clock.

8 U.S.C. §1427(b) primary source verified 2026-08-26

Physical presence is a TOTAL, and every day abroad counts against it verified

The physical-presence requirement is a sum of days, not a question about any single trip. Four separate two-month visits deplete it exactly as much as one eight-month stay, even though only the long stay puts continuity at risk. Somebody who travels frequently for work or family can therefore satisfy every continuity rule and still fall short on the total — which is the failure mode that surprises people, because no single trip ever looked like a problem.

8 U.S.C. §1427(a), applied primary source verified 2026-08-26

Deliberately absent: the exceptions for employment abroad with the US government, a recognised American research institution or certain international organisations, and the application that can preserve residence across a long posting. They exist, they are narrow, and anybody whose plan depends on one needs an attorney rather than a summary. Also absent is the other half of the statute — good moral character — which is not arithmetic and cannot be checked by a calculator. And a green-card holder planning a long trip has a second, separate line to worry about at the border: the one-hundred-and-eighty-day rule is a different statute with different consequences.

We already computed the public version — it is complete and stays free. Log each trip once and the Square keeps both running totals for you: Join DesiSquare and the Square remembers your dates, re-runs this when the rules change, and puts a credentialed human one message away.
