There are so many YouTubers and bloggers in Pakistan whenever they reach at the minimum payment threshold AdSense releases their payment every month.
There are several banks who accept Google AdSense payment in Pakistan but they charge a very high amount of money, so people are looking which bank charge the least. According to my own experience as a blogger I personally recommend you to open a Bank account in UBL limited they charge a very little amount.

No, it does not. AdSense last year said that they are not going to release the payment via western union, officially they did not mention any reason behind this.
