Direct family members of an EU citizen were/are not required to hold a residence card from another EU country or the UK to live or work in the UK.
As the UK government has made clear on their site.
https://www.gov.uk/apply-for-a-uk-residence-cardThe EU Directive also states that for Direct Family Members but makes it clear that an RC can just become invalid and the end date on an RC means nothing. UK rules allow UK visa holders to remain until their end visa date, but EU and UK rules are not interchangeable.
But as that link shows, having an RC will make it easier to enter the UK, show employers, ask for benefits, use UK services. Which is why people got an RC, especially if they are a non-EEA citizen Direct Family Member, even though the EU said they didn’t need one and they were lawfully in an EEA country if their sponsor was being a Qualified Person at all times. What else could a non-EEA citizen family member show an employer otherwise?
The reason employers want to keep a copy of an RC for a non-EEA citizen worker, is because they are then exempt from any fine or criminal charges for an illegal worker on their premises, even if that RC has become invalid. Only the holder of that RC will know if their EEA citizen sponsor is no longer a Qualified Person in the UK.
In 2016 the UK also made a new law that makes working when not allowed, a criminal offence for the person working too: fine, jail up to 1 year (6 months in Scotland and Wales), proceeds of that crime removed (the money they got from working). That same law increased the fine for the employer to 20k per illegal and made it easy for the Home Office to collect their fine, and the employer can now face jail of up to 6 years.
Extended family members are supposed to have one from the UK. https://www.gov.uk/uk-residence-eu-citizens/apply.
Extended Family Memebers must have a valid RC to be lawfully in the UK. Under EU laws there are no automatic rights for Extended Family Members and the EU merely asks that country if they can “facilitate” these. It’s why some EEA countries will allow non-EEA citizen unmarried partners and others will not and why these rules for EFM are constantly being changed in the popular EEA countries. e.g. the UK now saying EFM must be related to their EEA citizen sponsor and will no longer allow EFMs who were using their relative who is married to an EEA citizen.
The EU rules for EFMs mean these can only be in that EEA country lawfully under EU rules when that county
issues them with an RC. Non-EEA citizens who have to leave the UK as their UK visa is expiring and try to remain by putting in an application as an Extended Family Member under EU rules before their UK visa expires, cannot use the UKs 3C Immigration rule to keep their time lawful in the UK. If these remain in the UK after their visa expires and before their RC is issued, they are unlawful overstayers: can’t work, can’t use the NHS bill free, can’t drive; can be issued with a notice to leave the UK or be deported etc.
A few using the Singh route are now saying they have been issued with a deportation notice. Nan, was there something that says that those issued with a deportation notice can't use this settlement scheme? I can't rememeber if I read that or it's just something that is being said on the forums.
