I am a Singapore PR Holding Malaysian Passport. I just submitted my application of China Visa (Single-Entry Visa with 3-month Validity) this morning. Estimated I will get my passport back on this coming Friday. I believe that the date of issue indicated on this visa will be 17 or 18 or 19 March. For example, if the date of issue stated on visa is 19 March, is the expiry date will be 19 June?

1. From 19 Mar until 19 June, I can visit China any day?
2. How long I can stay with this Single-Entry Visa with 3-month Validity? I plan to fly to there on 10 May.

Kindly advise. Thank you
