请问HN：如何加快办理6月YC活动的B-1签证（英国申请）？
我受邀参加今年六月在美国举行的YC人工智能创业学校，我非常渴望能够参加。
我是一名居住在英国的学生，目前在伦敦上大学，持有埃及护照，这意味着我不符合ESTA的申请条件，需要申请B-1签证。
美国官方签证网站显示，在伦敦面试的等待时间为58天。此外，许多人在网上报告说，整个过程可能需要超过6个月，这远远超过了活动的日期。
我对这个过程还很陌生，似乎没有太多可以做的。我查过加急签证预约，但这些似乎只针对医疗、人道主义或重要商业情况（我认为这个活动不符合，因为它更像是一个会议）。我还没有提交DS-160表格，因为考虑到等待时间和不确定性，这感觉不太现实。此外，签证费用也有点贵，我在没有明确前进方向的情况下犹豫不决。
我已经收到了YC的邀请函，考虑无论如何请求加急预约。然而，我不确定这些请求的批准频率以及如何最好地提出申请。我以前从未独自旅行过，更不用说处理如此复杂的过程了。
这里有没有人：
- 成功从英国加急获得B-1签证？
- 在紧迫的时间表下处理过类似情况？
- 有什么建议或提示？
任何建议或见解都将不胜感激。我也直接联系了YC，但他们还没有回复，而我的时间已经不多了。

I’ve been invited to attend the YC's AI Startup School in the U.S. this June, and I’m very eager to attend.<p>I’m a UK resident currently attending university in London, and I hold an Egyptian passport, meaning I’m not eligible for ESTA and need to apply for a B-1 visa.<p>The official U.S. visa site shows a 58-day wait time for an interview in London. Also, many people online have reported that the entire process can take over 6 months, which is well beyond the event date.<p>I’m quite new to this process, and it seems there’s not much I can do. I looked into expedited visa appointments, but they appear to be reserved for medical, humanitarian, or important business situations (I didn’t think the event would qualify, as it’s more of a conference). I haven’t submitted the DS-160 yet because, given the wait times and uncertainty, it feels unrealistic. Also, the visa fee is a bit expensive, and I’ve been hesitant to commit without knowing if there’s a way forward.<p>I’ve received an invitation letter from YC and am considering requesting an expedited appointment regardless. However, I’m unsure how often these requests are granted or how best to approach them. I’ve never travelled on my own before, let alone dealt with such a complex process.<p>Has anyone here:<p>- Successfully expedited a B-1 visa from the UK?<p>- Navigated a similar situation on a tight timeline?<p>- Got tips or advice?<p>Any advice or insights would be greatly appreciated. I’ve also contacted YC directly, but they haven’t responded yet, and I’m running short on time.
