【正确答案】
The Visa Officer,
I enclose the completed application form for an entry visa to enable me to visit Singapore.
The purpose of my visit there is to join the world Linguistics Conference. I also want to gain some information about recent developments in education and visit some universities and colleges. I will guarantee my financial security during my stay in Singapore and payment of all expenses I may incur.
I have enclosed all my supporting documents. Should you require any further information, I shall be happy to supply it.
Yours faithfully,
James
