Do you need to go through the examination and approval procedures of geological prospecting for visa change?
No need. The examination and approval procedures for geological exploration are mainly applicable to the examination and approval procedures related to land use and construction projects. Visa change usually refers to the modification on the basis of the original visa, such as changing the visa type, extending the stay period, changing the visa category, etc. This change is usually handled in the immigration bureau, consulate or relevant immigration departments, and does not involve land use or construction projects.
