请帮忙翻译这段话，务必准确，签证的说明信用的

我已经购买了7月2日出发的机票，因为如果等到拿到签证再马上买第二天的机票可能会来不及而且难以买到特价机票。
I have bought an airline ticket and will set out on July 2nd, for it might be too late to get an plane ticket by the time when I get the visa, especially for an discount ticket.

如果可能的话请帮忙尽量快一点处理我的签证请求，最好能在这之前。
Would you please handle my visa application as soon as possible and better before my scheduled flight. your kind understanding will be highly appreciated.

I have booked the air ticket of July 2nd because it is difficult for me to purchase the ticket the day after I just get visa. I hope you can accelerate the process of my visa requriment and get my visa before July 2nd. Thanks

Since I’ve already bought my airline ticket and the plane due to depart on July. 2nd, could you please do me a favor to quicken your process in dealing with my visa in order to ensure that I could catch my scheduled flight. That is because if I buy the airline ticket after I get my visa, it might be too late and besides that, I could not buy the ticket at a bargain price. So please understand my situation and I’ll be really appreciated for that!
