签证还有很多，180天的咋说啊。
这个确实是好消息！又可稍微松口气！看看这个月的机票！
好消息，机票又是一大问题了，贵的飞起:’(
从来都没有说法
所以 我觉得 180 天是个软要求

那签证8月1日到期的就不能延期了吗？只能这么理解
的确没有发现180天具体的出处，官方也不曾提及：
If you held a visa that expired between 24 January and 31 July 2020 you were able to request an extension if you were not able to return home because of travel restrictions or self-isolation related to Coronavirus (COVID-19).
Now that travel restrictions are lifting globally you will no longer be able to extend your visa in the short-term and you are expected to take all reasonable steps to leave the UK where it is possible to do so or regularise your stay in the UK.
To allow time to make the necessary arrangements to leave the UK, if you have a visa or leave that was due to expire between 24 January 2020 and 31 August 2020, you will be able to stay within the UK until 31 August 2020.
From 1 to 31 August 2020 the conditions of your stay in the UK will be the same as the conditions of your leave.
If you intend to leave the UK but are not able to do so by 31 August 2020, you may request additional time to stay, also known as ‘assurance’.
