Attaches to a noun to indicate a role, status, capacity, or standpoint: 'as ~'. It frames the following statement from the perspective of that position or category. It can also mean 'in the qualification of' or 'considered as'.
[Noun] + として

として marks 留学生 as the capacity in which the person came.
彼は医者として尊敬されている。
Kare wa isha to shite sonkei sarete iru.
He is respected as a doctor.
として frames the respect specifically from his role as a doctor.
この城は観光地として有名です。
Kono shiro wa kankouchi to shite yuumei desu.

として identifies the category (tourist spot) in which it is famous.
• として + は adds emphasis or contrast ('as for in the role of ~'). • 私としては means 'as for me / from my standpoint'. • Register: neutral; frequent in both speech and writing.
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ~として is tested against.
にとって means 'for ~ (from the viewpoint of what matters to them)', while として means 'in the role/capacity of ~'.
In fixed negative phrases like 一日として…ない, として emphasizes 'not even one (single) ~', a distinct usage from the ordinary 'as a role/capacity' meaning here.
