Hi Zimba,
I cannot appreciate enough for your response.
Thank you so much for taking time and answering all the queries into such greater details.
I am sure it will help other seeking similar information.
I read somewhere that apart from 180 days (on rolling basis) there is also a maximum 540 days across 5 years.
In order to settle, you need to have not left the UK for more than 180 days in any of the five years (and you cannot have left the UK for more than 540 days in total - this will be checked during your ILR application) during your stay in the UK.
Since the same cannot be found in the official document I assume its untrue but please do comment on this as well
Regarding concessions during Covid Pandemic, I was in the country which was on the Red List and have returned as soon as the Country was lifted from it you are right I could have come and stayed in Hotel quarantine but since I was allowed to work remotely by my Organization I continued doing so.
Do you think it will be considered as a valid reason
On the similar note company are now being a lot restrictive against allowing foreign national in Tier 2 Visa to work from outside UK (remotely) I assume it is because its quite difficult to justify why Visa was issued in the 1st place / shortage Occupation List along with some UK tax implications.
They do allow working in short-lived duration like a week or so.
Is there any guidance / restriction from UK Home Office regarding the above rule ?
