英国的签证类型有哪些？
2015年4月英国新移民政策实施以后，分为两类： 1. Tier 1， including General Talent， Innovator and Start-up visa; HighlySkilledMigrant Programme (HSMP) converts to Talent Visa， Tier 1 (Post Study Work)， Tier 1 Entrepreneur and Tier 1 Exceptional Talent visa.
这些就是所谓的“移民签证”。在之前的政策中也有Tier 1的子类。主要区别是将以前的Post study work从PSW延长到PhD和硕士毕业后的三年，对创业和投资也做出了更严格的规定（例如不再允许以投资方式申请）；另外取消了之前的大部分子类，只剩下几个子类。
2. The other visas include： Tier 2 general， Graduate Trainee visa， Sponsor Licence， Student， Child student， Parent of a Student， Partner/Family Member of a Tier 4 Migrant， Tier 4 Dependant， Teacher， Sportsperson， Religious Worker， Seasonal Worker， Creative Worker， International Agreement Worker， Government Authorised Exchange Programmes， Global Talent ， Exceptional Casework， Business Visitor， Marriage Visas， Spouses or Partners under Refugee or Human Rights grounds，Dependent Children， Dependent Parents， Settlement / Indefinite Leave in the UK as well as some temporary visas such as Temporary Work ， Visitor， Pre settler etc. These are “temporary” visas for different purposes which can usually be extended up to five years. Some may lead to settlement， while most will not. This is what used to be called Standard visitor visa before April this year. 所有这些是“临时签证”，有各种不同的目的，通常可以连续续签最多五年。有些能转到移民类别而最终获得永久居留权；大多数则无法转入移民类别。这是今年四月新政策实施后以前的标准访问者签证。
