Can I apply china visa by myself without through agent?

Hi Rachel! You can't apply for it at the Singapore embassy. Instead, you should apply from the CVASC branch in Singapore. The documents you need to submit include your passport, a photocopy of the passport's data page, a fully completed application form attached with your color bare-headed photo taken within six months, the original and photocopy of your residence permit in Singapore, and round-trip tickets and hotel reservations. The cost is 65 Singapore dollars.
