SPELLING MISTAKE IN THE NAME ON VISA PAGE

Dear Sir,

I got visa to your embassy on Sep 10th, 2012.
My visa No. is F9058741.
My passport no. JA6894841.

My correct name is SHABBIR HUSSAIN
While on the visa you’ve written this SHAOBIR HUSSAIN. There is spelling mistake in the name on visa page.

Do you think I need to get correct my name to avoid any trouble?
Can you correct the name the same day since I’ve just one day left?
My air ticket is for SEP. 20th, 2012 so I want to visit your embassy on SEP. 19th, 2012 and want to get correction on the same day.

Awaiting your kind and soonest reply.
Your cooperation would be appreciated.

Thanks & B. Regards,
SHABBIR HUSSAIN
