Is there an online site in which to obtain a travel visa?

I am in Iraq and need to get a visa for a country that I would like to go to but our travel department doesn't do that for us. I was thinking that there might be a trusty site that I could get one fairly quick.

Google the official web site of the country.

There will be a site for visas.

yes type the coutry u want . using google. example how to get visa to china then there will be links

Go to this site:

No, there is no such site which provides online visa. You have to be present physically in the embassy to obtain visa. Nevertheless you can visit the source links if you wish to know about different type of visa requirements.
