The secretary of Homeland Security may designate a foreign country for Temporary Protected Status (TPS) if conditions in the country meet statutory requirements regarding ongoing armed conflict, natural disasters (including epidemics), or other extraordinary and temporary conditions in the country that temporarily prevent its nationals from returning safely. See 8 U.S.C. section 1254a(b)(1). USCIS may grant TPS to eligible nationals of a designated country, and eligible individuals without nationality who last resided in the designated country and are already in the United States. Individuals who are granted TPS are authorized to work. For additional information on TPS designations, please visit the TPS webpage.

The president may authorize Deferred Enforced Departure (DED) in his discretion and as part of his constitutional power to conduct foreign relations. Individuals covered by DED are not subject to removal from the United States for a designated period of time. Individuals may also request employment authorization if it is provided as a benefit of DED.

是否認定某國人民適用TPS是國務卿的職權
（潛臺詞是不適合返回的條件如果消失那該國也不再適用），
是否認定逾期居留人士適用延遲強制出境（DED）是美國總統的職權。
今天美國總統大發慈悲想當聖母也行，想當小氣鬼也行都屬於他的行政裁量權 (discretion)。
