Hi there,
If you read the requirements and all the paperwork on the travel.gov website once you sign into the website you will see that it is a requirement for ALL selectees to get a PCC from EVERY country you have lived in. So best to get cracking and get it done. Why risk your future and a possibility of being denied because you did not do the required steps to prove your eligibility? We had to get PCC for 4 different countries between my husband and myself. Took a while, but rather not risk it.
