Dear Sir,
I am a Singaporean applying for a visa to visit China. However I will not be flying directly nor will I be flying back from China. I am flying with Tigerairways and will be landing in Macau. As to your requirement about attaching a return ticket while applying for a visa, and at this moment I am still undecided as to when I will be coming back to Singapore, how should I do about it to apply a visa without a return air ticket.

Thank you.
