Hello: I want to ask for help. My sister's household registration is in Yunnan, my father's household registration is in Jiangsu, and my mother is in Yunnan. 12 can't I apply?

There are such regulations, and almost every province has similar regulations, mainly to restrict immigrants from the college entrance examination and protect local candidates. Think about it, if many candidates from developed areas go to underdeveloped areas to take the college entrance examination after receiving higher education, will the opportunities of candidates from underdeveloped areas be seized?

The regulation of Yunnan Province is that candidates from other provinces must meet the following three conditions before they can enter the college entrance examination in Yunnan. The first is that candidates must be registered in Yunnan for three years, the second is that one parent must be registered in Yunnan for three years, and the third is that candidates must be registered in Yunnan for three years. If the first and second conditions are not met, you can only apply to three colleges and universities in Yunnan after the college entrance examination (not three or less, you can't apply to one college). If you don't meet the third type of student status, you can only apply for colleges and universities in Yunnan Province after the college entrance examination.

As for the situation you mentioned, it depends on whether the household registration has reached three years, and if your sister and her mother's household registration have reached three years, then I can tell you responsibly that there is no restriction after the college entrance examination, and the father's household registration has no influence, because only one parent is stipulated.
