US state department in its annual report on international parental child kidnapping has pointed fingers at India effectively saying that India provides safe haven to parental child kidnappers. Thus India enables abuse of countless children brought from USA and other places outside India.
“India demonstrated a pattern of noncompliance by persistently failing to work with the United States to resolve abduction cases in 2015.”
If your estranged wife wants to take kids to India on “vacation”, use the state department report above to ask USA based judge to prevent your kids from being taken to India which will be a black hole for your kids.
