Rumor has it that the Rajesh Hamal look-alike guy who played his double in the movie "Gopi Krishna" had already been granted a US visa under passport-bearer name as "Mr. Rajesh Hamal" right before the real Rajesh Hamal applied for the visa. The consulate obviously concluded that the second application must be a fake one.
The moral of the incident is:
Do not act in a movie which has double, triple or more parts if you foresee yourself applying for US visa.
