If you do not want to (or cannot) continue the arrangement beyond six months, you should let the person or family you are hosting know in plenty of time so they can make other arrangements.
Os nad ydych am barhau (neu’n methu parhau) â'r trefniant y tu hwnt i chwe mis, dylech roi gwybod i'r unigolyn neu'r teulu rydych yn ei letya mewn da bryd fel y gallant wneud trefniadau eraill.
