I hope someone can help me with this.
My Ex GF was issued with deportation papers from the UK to Colombia on 27 May 2010 and left on 2 June 2010.
The UK gov paid for the flight.
I understand there is a 10 year automatic ban so that has now expired.
She does not have any criminal record
She wants to return to the UK to visit in 2023. ( she has not tried to visit in the last 10 years )
Normally you would apply for a visa to visit the UK from Colombia so would be able to present
documents regarding her previous removal and reasons why she will return to Colombia and not overstay this time
She has a business in Colombia and will need to return to continue to run the business.
But in November 2022 you no longer need a visa to visit the UK from Colombia as a tourist so
1) Would there be any problem with her just arriving at the airport and being granted entry.
is this going to be 100% successful
2) Should she apply in some way for a visa to get paperwork showing she had been approved entry after
presenting her old removal papers. If so can you point me to the information detailing the process.
I have attached an images ( suitable redacted ) that provide the specifics of the removal should this be of use.

Thanks for your time
Trevor
I did try doing some searches around "10 year deported" but there are lots of results and I did not see any covering this situation but happy if you can point me to similar questions.
