如果持有欧盟家属签证，但是相处一段时间不合适分开，发现怀孕，如果离婚后是否可以申请福利
如果你们的关系结束了，法律上你的EEA也就失效了。要是你的前欧盟配偶向UKAB报告你们关系结束，UKAB会立即终止你现有EEA的有效性。即使你的那位现在不向UKAB说，但以后也是隐患。技术上讲你已经没有资格拿着EEA在英国待着了。至于福利嘛，您说呢？

If you are a non-EEA national who has been living in the UK on the basis of your relationship with an EEA national, can you stay in the UK if the relationship ends?
If you were related to an EEA national by marriage or civil partnership but the relationship has ended through death, divorce, dissolution or the EEA national’s departure from the UK, it is possible that you will retain a right of residence in the UK under European law. For more information, phone our European enquiries contact centre and speak to one of our advisers.
If you were the unmarried partner of an EEA national and the relationship has ended, you no longer have the right to live in the UK under European law.
虽然某些情况也许可以继续待在uk，但eea2 5年过期后需要申请permanent residence的时候要求是过去5年是不靠福利的，而且还要看relationship的证明以及eu partner的passport/id card来证明对方对自己的支持。
When you have lived here for a continuous period of 5 years with the EEA or Swiss national (who must have been in employment, self-employment, studying or self-sufficient in the UK throughout the 5 years), you can apply for confirmation of your right to permanent residence in the UK.
另外以照顾eu national child的理由的话，此child也要求是self-sufficient（不靠福利不靠监护人的工资，除非监护人有自己单独的非eea下的工签），而且此情况监护人得到的leave不可以work也不可以申请pr（这和discretionary leave to remain是不同的）
I am a non-EEA parent or primary carer of an EEA national self-sufficient child - can I apply to remain in the UK?
Following the ruling by the European Court of Justice (ECJ) in the case of Chen (ECJ C-200/02) the parent(s) or primary carer of an EEA national child is entitled to reside in a Member State with a self-sufficient EEA national child solely to facilitate the child in exercising their Treaty rights. The child must have comprehensive sickness insurance and be self-sufficient. This means that they must not rely on funds earned by a non-EEA national parent(s) or primary carer in the UK, unless this comes from legal employment or self-employment (if the parent(s) or primary carer is in the UK on a work permit).
In cases where the non-EEA national parents or primary carer wishes to reside in the UK on the basis of their relationship with an EEA national self-sufficient child, then they can apply for leave to remain under paragraph 257C of the Immigration Rules. The leave granted does not allow the parents or primary carer, the right to work in the UK and does not lead to permanent residence or indefinite leave to remain. Applications made on this basis are free of charge and should be submitted on an EEA2 form.
