Mae’r canllawiau’n nodi’n glir nad yw’n bosibl rhagweld pob cais i ymweld ac mae’n cynnig darpariaeth ar gyfer amgylchiadau eithriadol sy’n caniatáu ystyried ceisiadau ar gyfer ymweliadau nad ydynt yn cyd-fynd â’r categorïau yn y canllawiau gan edrych ar amgylchiadau unigolion, ond gan ddilyn y prosesau asesu risg lleol.
The Guidance is clear that it cannot foresee all requests for visiting and contains an exceptionality provision to allow requests for visiting that are outside the categories listed in the Guidance to be considered taking into account individual circumstances, but still following local risk assessment processes.
