hi.. not to worry... this is not sth difficult. i had 2 go thru this n its fairly simple. at least it was last year.
all U need 2 do is go 2 our embassy, n apply 4 the police clearance certificate, give in copy of ur passport. its upto them 2 contact the state wer ur passport was issued n follow up n ensure if the records r clean.
after dt they'll issue the certificate which will need 2 b attested by the Minstry of Foreign Affairs. Take this 2 the Labour Dept. Whole process hsud not take more than a week, max 10 days.
Good luck..
