I'm about to book a side trip from China to Mexico and back. From experience both the prices and the number of entries and duration per entry China will grant you actually vary quite a bit depending on where you are from and in what country you apply for your Chinese visa. For instance:
The times I got my Chinese visas in Laos they were half the price or less than what I paid in Australia.
But this time in Australia I was granted 60 days per entry.
Once I changed my plan to get a Chinese visa in Vietnam because they would give me only one 30-day entry. I went back to Laos and got two 30-day entries.
What really are my options at the consulate in Mexico?
