How long does it take to be approved by Adsense

depends on the number of applications they receive.

Mine was accepted in 2 days. But sometimes it can take a week or two.

Varies.

I got accepted into adsense in 4 hours straight!
But a friend of mine had to wait one whole week to get accepted.

As already said, it depends from time to time. It took almost 5 days for them to accept me.

it depends on type of content

still u should get reply within 8 days , if not mail them back,

but expect any mails from google if you are doing anything wrong.

Another important thing is if you use Yahoo or hotmail check your bulk/spam mail folders. Google emails sometimes fall into these folders.

Thanks guys the site was approved.
