return to work

I just started a new job this week at an assisted living facility. Its going ok I guess. Its a nice place and the staff and residents seem friendly. Of course there are problems like the pay is'nt the greatest, there are no benefits and they are still short-staffed, but at least its a job. Anyway, I have a weird question. How soon do you have to let the unemployment agency and the student loan center know that you have a job? I assume with the unemp. you can just file the weekly claim and put change of hours-accepted work on the form. The only info I found in the booklet was you are suppose to let them know when you are offered work. I did'nt do that since I accepted it already. For the loan company, I have one loan deffered and the other one in forebarence. It would be nice to keep them that way for a couple months so I can get caught back up on bills a little and maybe get a little cushion (which I never seem to have). But I don't want to get in trouble for not reporting it right away. I'm not sure what they can do (I don't want my credit affected or anything). I guess I'll just call them next week and let them know and see what my options are. I don't think it was a big deal I did'nt let them know this week as I only trained for 3 days, but what do you guys and gals think?
