I came to the UK as a student and graduated with a Bachelors degree from a university and subsequently enrolled for a PG Dip in a private college due to it's reasonable fees and graduated earlier this year. I then applied for IGS after graduation and was granted the visa a few weeks later. Last month, I was told by on of my classmates that the college is now closed and removed from the Dfes register after they were caught for something dodgy. Speaking to the college, I was told that they are now under new management.
I was granted a PG Dip from the old college this year as I studied there for about a year and now they have even been removed from the list of listed bodies. As far as I know the college was fine,there were about 60-80 students and the teaching was not bad but facilities weren't great.
I am now working under the IGS visa and would like to possibly extend it to PSW or WP before the expiry but, I am a little confused here with the college closure and validity of my certificate now. Where do I stand?
Any advise will be much appreciated as I'm a little confused here of what to do

Thanks
