The government should clearly state whether it is appropriate for officials to hold a U.S. green card or U.S. citizenship, opposition Democratic Progressive Party (DPP) Chairwoman Tsai Ing-wen said Saturday.
The government should make a decision on the issue and inform the public of its decision, she said.
If the government believes that holding a green card will not interfere with a government official's exercise of his power, it should offer a clear explanation of why this is so, she went on.
People have a right to know which officials still have a U.S. green card or had the card before, Tsai claimed, adding that the government should make public the names of officials with a green card just as it requires public servants to declare their assets.
Tsai made the remarks amid an ongoing campaign initiated by DPP lawmakers to challenge the allegiance to the country of several officials in the Kuomintang (KMT) administration who either had or has a U.S. green card, or have applied for a U.S. green card.
Taiwan's Nationality Act forbids local nationals with foreign nationality from assuming public office and requires those with foreign nationality to be removed from their posts.
However, it does not forbid public servants from holding permanent residency of a foreign country.
