Adsense will always approve blogs as long as they meet the requirements. On their site, it is stated that a blog that is hosted in India or China will need 6 months ownership before they can be approved. This rule of thumb doesn't always apply and some blogs have been approved even though the site is only owned for 1 month. When they say site owned they are talking about your domain name. How you can get approved even though you don't have a top-level domain:
Sufficient Content: Your website should have a sufficient amount of content before applying for AdSense. While there's no specific word count requirement, having a few well-developed pages or posts can demonstrate that your site is substantial and valuable.
Quality Design: Your website should have a clean, professional design that offers a positive user experience. Easy navigation and clear organization are important.
