Indonesians in Taiwan form one of the island's larger communities of foreign residents. There are 144,651 people who have nationality of the Republic of Indonesia reside in Taiwan as of December 2010. This includes 19,554 males and 125,097 females, with 136,679 people serving as foreign laborers.
26,980 Indonesians (many of them with Chinese ancestry, such as Hakka people) had immigrated to Taiwan through international marriage, mostly female, and some had naturalized into ROC citizenship.
In Taiwan, employers can be fined if they force Muslim workers to come into contact with pork, something forbidden by the Muslim religion that most Indonesians profess. In Chiayi City, a couple was fined for doing that to an Indonesian worker, in addition to other offences such as an imposing a long workday, and threats of deportation.
In 2013, an Indonesian worker, who is married to a local Taiwanese man, built a mosque called the At-Taqwa Mosque in Dayuan Township, Taoyuan County (now Dayuan District, Taoyuan City) to support the growing number of Muslims, especially from the Indonesian workers community.
