I've read a few criticisms in regard of visas once here in China. My own experience has been a good one. Initially I had a 6 month visa to stay in China. Enfly helped me to get another 6 months here, without any problems. In fact, it couldn't have been easier. Clear advice and full support enabled me to complete my application in an afternoon. I was reimbursed payment for the visa almost immediately. The visa office is just around the corner from Enfly HQ too!
