GUARDING AGAINST THE INVISIBLE ENEMY Lian Zhimin, Arvinder Singh, Rayna Tan & Tan Chermel Immigration & Checkpoints Authority ABSTRACT The emergence of the Coronavirus Disease 2019 (COVID-19) prompted many countries to impose stringent border control measures to mitigate the risk of importation of the infectious disease. Singapore was no exception. To guard against the invisible enemy, the Immigration & Checkpoints Authority (ICA) implemented tighter border control measures within a short span of time, constantly adjusting them to mitigate the fluid situation. As the global situation worsened, Singapore took the unprecedented step of closing its borders to short- term visitors. ICA also had to conduct heightened clearance operations for dedicated flights that brought home stranded Singapore residents from around the world. In anticipation of a protracted fight against COVID-19, ICA leveraged technology and fine-tuned its operational processes to alleviate the workload of the frontline officers. Beyond the borders, ICA was also responsible for implementing and enforcing the Stay-Home-Notice (SHN) regime to minimise the risk of community spread from residents returning from overseas. Many ICA officers also volunteered to be part of the Forward Assurance and Support Teams (FAST) at migrant worker dormitories to enforce Circuit Breaker Measures. This article documents ICA’s response to COVID-19 as guardians of our borders, protecting more than just a line on the map. It also describes how ICA adjusted a border control regime primarily designed to deal with security threats to manage COVID-19, providing a glimpse of border control in a post-COVID-19 world.

For example, in 2018, ICA and MOH SAFEGUARDING PUBLIC HEALTH staged a joint exercise codenamed Exercise Sparrow Hawk to implement effective health screenings at the The Immigration & Checkpoints Authority (ICA) was land checkpoints. formed in April 2003 against a backdrop of heightened security risk arising from the 9/11 terrorist attacks in The Coronavirus Disease 2019 (COVID-19) is, the United States.
