Firstly,to the filipino/uk forum.
Secondly, I'd like to give you 'a lttle' (excuse the pun) reassurance... based on your father-in-law's Filipino wife's travel history up until now - assuming she fully complied with the Ts & Cs of each of the tourist visas granted to her in the past - which would, on the face of it, augur well for any subsequent visits.
Thirdly ... given the serious nature of her husband's illness - and his resultant indefinite period of hospitalisation - it MAY be feasible for her to make application to the British Embassy in Manila, on compassionate grounds. Equally, it *MIGHT [*again]be possible to arrange this through the Home Office.
