There's an organisation - something like Parents Of Children Abroad - which offers advice mainly to parents whose child have already been taken by a separated spouse who lives in another country. Don't know what it is called, but you could Google it, as they may well have advice to offer. I heard heartbreaking interviews on a radio programme with mums whose kiddies were abducted by an ex and then who lost all rights to see them, let alone get them back. There is an international convention to ensure that children are returned to their home country, but it doesn't always get enforced and not every country is a signatory. Well worth checking out before she makes any decisions.
