Many families with one or more US citizen parents are familiar with the rules governing the transmission of US citizenship at birth when their children are born outside the US. Particularly, to transmit citizenship the US citizen parent must have generally spent a specified period in the US before the child’s birth. However, there is a lesser-known pathway that may allow children living outside the US to obtain US citizenship after birth, even where the physical presence requirements were not met at the time of their birth.

Overview of INA 322
The Immigration and Nationality Act (INA) section 322 provides a mechanism for certain children residing outside the United States to naturalise as US citizens after birth, typically through a US citizen parent or, in some cases, a US citizen grandparent.

This process is distinct from citizenship acquired at birth under INA 301, which requires the US citizen parent to have met specific physical presence requirements before the child’s birth.

Physical presence requirements: a key distinction
A central feature of INA 322 is how it treats the required period of physical presence in the US. The statute (8 USC. § 1433) requires that the relevant US citizen parent or grandparent “has been” physically present in the United States for the requisite period (generally five years, including at least two after the age of 14). Importantly, the law does not require that this physical presence be completed before the child’s birth. Instead, the requirement may be satisfied at any point before the application is approved and the child takes the oath of allegiance, provided the child is under 18. This reflects the nature of INA 322 as a post-birth naturalisation process, rather than a transmission of citizenship at birth.

Practical implications
This pathway can be particularly valuable in situations where a US citizen parent did not meet the physical presence requirements at the time of the child’s birth, but later accrues sufficient US residence after the child is born. Alternatively, the required physical presence can instead be met through a US citizen grandparent’s physical presence in the US, even after the child’s birth. Families may previously have assumed that citizenship was not available, based solely on the rules applicable at birth, therefore a full assessment is imperative.

In order to naturalise under INA 322, the child must be under the age of 18 when the process is completed. Applications are made using Form N-600K, and the child is generally required to attend a naturalisation interview in the United States. Children often travel to the US for this purpose as visitors, with the expectation that they will return to their residence abroad following the process.

Why this matters
INA 322 offers an important alternative for families with ongoing ties to the United States who may not have met the requirements for citizenship transmission at birth.

Given its more flexible timing rules, it can open up possibilities that are sometimes overlooked in initial citizenship assessments.
