Some of the major hurdles which i identified in the extension process when one has worked overseas for most of the grant period are :-
1> Entering UK with limited leave to remain on the Visa.
To clear the immigration check smoothly one needs to showcase the intent of living and working in the UK. So any proofs associated with a scheduled job interview or intent to look for a job while in the UK should definitely help. I am not sure if entering UK with a one way ticket may help ..suggestions?
2> In person applications are not granted the same day or takes longer.
I believe this can be only helped by improving the quality of the documentary proofs submitted. The other option is to apply through post which may not be feasible if one has plans to leave UK post extension.
Some documents that I think may help the process:-
- Employer’s reference letter to prove your status of employment.
Tax slip/receipts to showcase your tax status in the foreign country.
Any foreign Id proof for your resident status in the foreign country.
If submitting a foreign bank statements then back it up with a letter from the bank on its letterhead confirming the authenticity of the statements.
Also inform your employer/Client in advance about a possible background verification by UKBA and ensure they respond quickly and in the affirmative.
Points to note:
1> Using overseas earnings for Tier 1 extn should be done without using any upliftment i.e. direct conversion of foreign earning to GBP.
2> Any stay outside UK for a period more than 90 days may impact the chances of ILR.
PS: This is my understanding of the process and it is possible that I may have missed or misunderstood something. This is just to collectively understand the complexity of the process and one must draw their own conclusions based on their situation.
