I initially had a 1-year Tire 2 General visa. After my company extended my CoS for 3 more years, I recently applied for an extension. After receiving the new BRP, I found that I've received only 2 years of extension whereas my new CoS expires after 3 years.
After extensive search on the immigration boards portal(thanks to you guys

Or I can apply for another extension after my visa near to end for another time. As per today's situation, my company is willing to give me a visa till I get settled here in the UK. I hope this will not cause any problem when I apply for the ILR.
Thanks.
