There is a question on the UK visa application asking if If I have been "required to leave the UK" and I'm not sure if I have been or not.
So, the story is:
I hold a Hong Kong passport which grants me Visa-free to the UK for 6 months.
I first arrived in the UK as a Visitor on 31st Oct, 2019 with my boyfriend. My BF is UK citizen. The office just asked me some general questions and gave me a stamp (refer to pic 1) saying "Leave to enter for six months" from Heathrow airport immigration. He didn't ask if I have a return flight ticket to HK.
After couple months, I left the UK for Amsterdam with my BF for a short vacation on 27th Dec, 2019 and re-entered the UK on 29th Dec, 2019 at Belfast airport.
This time, the immigration officer gave me a hard time after learning I didn't have a return flight ticket to HK (plus, I think it's because my BF's attitude wasn't that nice to him). He took my passport and detained me and walked away (I guess he went to the office). After he came back, he interviewed my BF not me. After the interview, he said to my BF there's two options: (1) send me back to Amsterdam right away and (2) I can enter but have to leave the UK by 31 Jan 2020.
Of course he chose option 2, and got a stamp similar to the one from Heathrow saying "Leave to enter for/until 31 Jan 2020" (refer to pic 2)
Other than that, he didn't give me any documents or anything.
Does that mean I was required to leave the UK?
