@Nilgiri, I am sending a copy of the information that I have that says about 500,000 Indians are working in BD and they send about 3.71 billion to their families. I think, the reason is what you have stated, i.e, they fill in the positions BD people cannot.
Many thousand Sri Lankans as well are also working with the textile sector. Many more Pakistanis will also be coming once businesses there move to BD. It is a very natural phenomenon.
These
skilled Indian workers in BD contribute to our textile industry and in our economy. There are Nepalese in India, but, there are Indians also in Nepal who contribute to Nepalese economy.

5) Bangladesh
Bangladesh is a developing country and is the eighth most populous country in the world. It is reported that there are Indians who are staying in Bangladesh and there are about 500,000 Indians presently residing.
People who are migrating to Bangladesh illegally are from West Bengal, Meghalaya, Assam, Tripura and Mizoram. According to the government authorities of the country, most of them come in search of job opportunities and mostly work in NGOs, garments and textile industries.
These Indians remit $3,716 million to their home country and the number is expected to increase in next few years.
