I would like to ask several questions regarding ILR application
So I have stayed in the UK for almost 9 years (Tier 4 student visa + Tier2 general) and I want to apply for ILR using the Tier 2 one. Below are the questions:
Nationality : No problem with this as I successfully applied for UK visa many times ( I always use Hong Kong here)
Life in the UK test: Pass but nationality there a bit different from my current one (staff there told me to
change to China, I accepted that but in visa applications china and Hong Kong are always two different options, let alone HK BNO)
Absence information: my current tier 2 started on 23/01/2019 and expires on 01/04/2024. So I just need to input the absence info during this period right? And regarding when did I enter the UK, I should just put the tier 2 one even though I were living in the UK before this tier 2 period, right?
Evidence to support the absence leave: My leave is holiday so just choose "Letter(s) from employer(s) detailing reasons for work-related absences including periods of paid annual leave from the UK and Crown Dependencies"
Sponsors: Currently I have one full-time and one part-time job. They have different employers but the jobs have the same type. My current Tier 2 visa is associated with the full-time job. Therefore, I just need to input the full-time job sponsor info right (the salary in this job is already above the requirement)? My part-time job is provided by a Top 3 UK university (they said 2 jobs for Tier 2 was ok so I trust them

Previous Immigration history: I can provide the Case number for my current tier 2 but tier 4 ones probably loss, so I guess I do not need those right?
Thanks
