My brother is getting married at the end of the month in US, where we are citizens, and of course I wish to attend. But I am in middle or PR application and nervous about leaving messing that up. Do I need to get permission or inform immigration of my intent to leave? Otherwise could I be denied entry back into the country? My kids and husband (who are canadian citizens) would be staying behind in Canada (where we've lived for the past year) Thanks in advance for any guidance!!
