Argentine Antarctica mainland. Argentina was the only nation to have an Antarctic base for 40 years until the British built a base on the same islands. Argentina bases its claims on this sector of Antarctica on the following grounds: Argentina's claim to the Antarctic Peninsula overlaps with the Antarctic claims of Chile, 53°W to 90°W, and the UK claims, 20°W to 80°W. Currently, there are no attempts by Argentina or any other country to enforce territorial claims in Antarctica. See List of Antarctic territorial claims. None of these claims have international recognition and have been suspended by the Antarctic Treaty in 1961.
Permanent residency However, in Singapore, most first generation permanent residents are exempted, and only their sons are held liable for NS. In a similar approach, the United States has Selective Service, a compulsory "registration" for military service, which is required of all male citizens and permanent residents ages 18 to 26; this requirement theoretically applies even to those residing in the country illegally. Applications for citizenship may be denied or otherwise impeded if the applicant cannot prove having complied with this requirement. Permanent residents may be required to reside in the country offering them residence for a given minimum length of time
