I am wondering how could some one send his/her passport if required for the PR stamp? I am in US and have applied for myself and my wife's immigration. Say if approved, how would I send my wife's passport here in Detroit as it is illegal to send passport via mail and she could not come here to US either? This is a new pratice and the consulate used to mail the landing papers before, instead of asking the passports in original for the stamp process.
