why don't you come here and count( if you can count). After all they were your citizen before entering India( they enter before Dec 16 1971 so they came india before bangladesh created as east pakistani. Yaa many came after that too and still coming too) and take back with you in pakistan. After seeing your sympathy towards bangladesh in PDF, I hope that you will treat them well( not like before 1971) and this will show your change of attitude towards bangladeshi( former east pakistani)
Classic Indian off-topic troll post. By all reasonable estimates, the number of illegal Bangladeshis is somewhere between 2-3 million.
