So far there only seems to be one googlebot, and it crawls from the US. You'd expect there to be one from every country, but nobody has seen them yet.
So if you want googlebot to see only the .pk version of the site, you have to put an exception to the redirect. If the visitor is from Pakistan OR from google, show them .pk. If the visitor is from elsewhere AND is not google, show them .int.
This may be a problem if google has already seen .int. And it might be a problem for people outside of Pakistan doing searches that lead to your site.
