So there has been some development to this now:
The husband passed away just 2 days ago...
The husband and the other wife and youngest son were in canada recently and from what I understood since my SIL has no idea what type of immigration they went on, applied for change of status in canada. However the husband got sick and was admitted in the ICU twice a month and a half ago so the second wife sent him back to Pakistan. The wife stayed behind but sent the kid. The husband came back and few weeks later got very sick and had a heartattack and was admitted in ICU. Eventually the doctors told the family in Pakistan that he had only few days left to live. So that said, he passed away yesterday in Pakistan while his other wife was in Canada. Now she is returning and not sure what her canadian status will be but I believe she was working and had submitted her passport.
Honestly I don't care about what will happen to her and her kid. Now that my SIL is widowed and she has 2 daughters, can we go ahead and complete the i130 application process? If yes, then do we need her husband's death certificate at this stage?
What is the overall processing time from stage 1 to all the way to embassy stage? Are we looking at 7 to 8 years? does anyone know what year is Pakistan embassy is currently working on for F1 visa category? Would her having kids come into play here? Her daughters are 12 and 18 so what are their chances of immigrating with their mom under CSPA?
TIA
