Angeleyes, I had come crossed the same problem while back. First of all call the Nepalese Embassy in Washington, D.C. asap . . . good luck . . . people working in the visa section are not courteous and may give you a hard time. Inform your local police and get the report from them that your passport has been lost. A time frame for getting another passport depends solely on your verbal communication skill with the Nepalese Embassy. If you can talk your way thru and convince them that your passport has indeed been lost you will get another passport. Good luck . . .
