PF withdraw while changing job

Hi,

1. If a person leaves a job and immediately joins another company, can he withdraw the PF amount of the earlier company ?

2. In my case, the last company was regular non-trust but the new company is under exempted category (trust). In the UAN portal, I am not finding any options (like form 19, 10c etc.).

Can any one give a solution under what circumstances I can withdraw the previous PF amount ? And what should be the process?

thanks,

Som
