What type of agreements may the Hong Kong Special Administrative Region conclude with foreign states regarding visas?

The correct choice reflects the specific authority granted to the Hong Kong Special Administrative Region (HKSAR) under the Basic Law concerning its ability to negotiate international agreements. The HKSAR has the power to enter into arrangements with foreign states on issues related to immigration and related matters, including the establishment of visa abolition agreements.

Visa abolition agreements allow for the mutual removal of visa requirements between Hong Kong and other countries, facilitating travel and strengthening ties. This aligns with the HKSAR's function as a separate customs territory and its autonomy in managing immigration policies, thereby enhancing its ability to engage with other nations effectively.

While the other types of agreements mentioned may sound plausible, they do not pertain specifically to HKSAR's recognized rights under the Basic Law concerning international agreements. For instance, visa extension agreements and visa acquisition agreements would typically fall under domestic law and administration rather than international agreements. Meanwhile, visa limitation agreements could imply restrictions that might not align with the objective of establishing beneficial relationships through mutual visa abolition. Thus, the focus on visa abolition agreements accurately captures the HKSAR's capacity to forge agreements with foreign states within the framework of its autonomy.
