Can Aksu's hukou take the college entrance examination in Urumqi?

You can take the college entrance examination. As long as you have a complete student status in Urumqi, you can take the college entrance examination in Urumqi, and the school is willing to accept you as a student.

I can't tell the specific basis. My household registration is Aksu, and I took the college entrance examination in Urumqi that year. Think about the schools in Urumqi that recruit students from all over Xinjiang, such as Experimental Middle School and Corps No.2 Middle School. If students can't take the college entrance examination because their registered permanent residence is not in Urumqi, they can't enroll students in Xinjiang.

In addition, it is not called college entrance examination immigration for Xinjiang candidates to participate in the college entrance examination where they are not registered, because the overall educational conditions and college entrance examination admission in Xinjiang are an environment, and exams outside Xinjiang are called college entrance examination immigrants.
