Iam preparing to apply for FSWP. My previous company (which i left 5 years ago) has closed its business now. To get full experience points i need to include this experience . I have all the documents like appointment letter, pay slips, pay rise letters, termination letter which i can send to cic as proof of work. My worry is that when CIC will try to call the company for verification, they will not be able to get in touch. Can this cause any problem?
