travel airport check urgent

hi

i have just finish my assessment at uni and my course begins in feb. i need to go home asap due to some personal reasons for 1 week.?

are they still checking NI at airport? am working only 20 hrs now but last yr , i might have overwork in around may - june?

any advice on airport check if i come back in 1 week?

if they do check, what documentation shud i provide? my current payslips+ uni letter??

please help

The documents you suggest will be useful but there will only be a oroblem if you worked consitently in excess of 20 hors per week. If you are asked what hours you have worked it is not a good idea to withold information.
