My wife (US Citizen) and I moved from the USA back to Northern Ireland where I am from in 2018, My wife now currently has an EU Scheme Pre-Settlement Residence Card (work permitted/ leave to remain) that was issued in the UK April 2021. We have been back in the USA since March 2022 and plan to return to Northern Ireland in the Summer/Autumn of 2024. As I understand it my wife will need to return to either the UK or Ireland before she has been gone for a total of two consecutive years to maintain her residency, she is planning on returning next year February 2024 for a week/ 10 days
The UK’s EU Pre-Settled Status is Limited Leave to Remain.
If you were hoping for your wife to obtain the UK's EU Settled Status when you return next year, those 2 years abroad allowed for those on Pre-Settled Status does not let the applicant meet the requirements for Settled Status.
To be able to apply for Settled Status, it’s only 6 months in any 12 months, to be able to meet the “
continuous residence” requirements to apply for Settled Status.
"How your continuous residence is worked out
Five years’ continuous residence means that for 5 years in a row you’ve been in the UK, the Channel Islands or the Isle of Man for at least 6 months in any 12-month period."https://www.gov.uk/settled-status-eu-citizens-families/what-settled-and-presettled-status-means"The 5 years is counted from the day you started your continuous residence, not the day you were granted pre-settled status.
You may not be eligible for settled status if during the 5 years you spent more than 6 months outside the UK in a 12-month period."https://www.gov.uk/settled-status-eu-citizens-families/switch-from-presettled-status-to-settled-statusShe might get the new 2 years added on to her Pre-Settled Status, because the EU said those who used their rules to live in the UK are low skilled and won't remember to renew their visa and could become overstayers.
During that time/2 years extra time, Pre-Settled may remain valid. Those who can qualify for Settled Status can apply for Settled Status. Those who can't make the requirements for Settled Status of 5 years of
continuous residence, can look for another visa to be able to continue to live in the UK.
The question that I need help with is should she enter back in through a UK Airport (port of entry) or if she enters through Dublin Airport will it suffice and will there be a record that she entered back in?
As the UK left the EU, it will be up to the Republic of Ireland if they let her in at Dublin. The UK's EU Settlement Schemes means nothing to the Republic of Ireland just as the EU's Free Movement/EU Residence Cards/EU PR, meant nothing to the UK from 1 January 2021.
