It'll need expert lawyers. Here is the "concentric" piece of Bangladeshi law that deals with Citizenship by Descent: http://bdlaws.minlaw.gov.bd/sections...ctions_id=7472

--------------------------------------
5. Subject to the provisions of section 3 a person born after the commencement of this Act, shall be a citizen of Bangladesh by descent if his 1[ father or mother] is a citizen of Bangladesh at the time of his birth:

Provided that if the 2[ father or mother] of such person is a citizen of Bangladesh by descent only, that person shall not be a citizen of Bangladesh by virtue of this section unless-

(a) that person's birth having occurred in a country outside Bangladesh the birth is registered at a Bangladesh Consulate or Mission in that country, or where there is no Bangladesh Consulate or Mission in that country at the prescribed Consulate or Mission or at a Bangladesh Consulate or Mission in the country nearest to that country; or

(b) that person's 3[ father or mother] is, at the time of the birth, in the service of any Government in Bangladesh.
