Hi,

Can I apply Tier 2 General visa from Tier 4 General Visa. Can I switch the visa after current student visa expires? I've got an offer from an company and willing to apply Tier 2 General Visa.
I heard that I can make Fresh Tier 2 Application even after current visa expires but no later than 28 days. So, I can make the application within 28 days of my current visa expiry date? Am I right?

Could anyone help me out.
