I'm a US (and Irish) citizen who immigrated to Canada with my entire family in 1967. After leaving and returning several times due to my father's work, I went all through high school in Ontario (1972-1976, grades 9 through 13). Since then I have lived outside of Canada for about 40 years. Recently, I came to Canada in June of 2016 and have been in Canada for over two years continuously so I have met the Residency Obligation requirement and want to apply for a Permanent Residency Card. However, my main concern is that contrary to some of the advice given in the forums here not to contact IRCC for anything during the RO period I DID apply for a visitor's extension and then applied for a reinstatement after the extension expired, and that extension expires September 30, 2018. The reason I gave on the reinstatement application for not reapplying prior to expiration is that I wasn't sure if I even needed to apply for a visitor's extension this time or the first time as I was a landed immigrant, and I submitted a scan of my 1967 Canadian Immigration Identification Card along with a scan of my SIN card. Consequently, I was assigned a UCI number. Should I put my UCI number on the Application For A Permanent Resident Card and did I mess things up for myself by applying for a visitor's extension?
