Need advice 3c route
So my cos is with home office for renewal. My manager has applied on 20th march. June 6 is when my visa expires.
So the COS is still not here. This is an extension case, last time it came on 22nd may because my employer applied for license.
Can i apply for my visa without cos. Add cover letter, proofs etc for cos.
I need to know how risky it is. Please tell me when should i apply also if someone has done it added cos later how and what they did.
