I am a Tier 2 General Primary Applicant , My in laws visited UK yesterday in Family Visitor Visa with the validity of 180 days, In the heathrow airport the border force immigration officers have asked about the return date, they weren't too sure at that time when they are gonna return back(definitely not a plan to extend / over stay), they just randomly mentioned 2 months, the officer has mentioned that they should not stay within UK beyond July 15th ( 2 months from arrival) , If they do then my Tier 2 general visa will not be renewed as it is due next year, Is this just a threat? Will the 180 days visa validity overrides with 60 days dutaion given by border force Airport immigration officer ? They haven't mentioned this anywhere in the passport, but officer has mentioned that she will note down in the system, which may impact the renewal.
Now my daughter wants her grandparents to be there on her birthday in September , Will that be not possible ? Should they return back before July 15th ? Is this a risk?Please assist
