It is advisable that
you apply for a visa one month before your intended date of entry into China
but not earlier than three months. The Chinese visa is typically valid for
three months. If you apply for a visa too early, the visa may expire before
your departure. For instance, if you plan to enter China on July 1, the best
time to submit your application would be around June 1 (counting working days
only).
Please note thatunder certain
circumstancesthe validity of visas is equal to or shorter than
one month. In that case, you may apply for the visa around two weeks before
your intended date of entry into China.
