hi anerr777,
i'll try to answer some of ur questions with the little knowledge i ave abt FSW1
first i think u shd apply from naija,it'll b easier for u 2 gather ur docs as long as u ave someone in naija dat can follow up 4 u as per d docs,PCC n stuff.
second,u only need letters from employers of jobs u r claiming points
third,they will not need ur sal account,only need a savings or fixed dep in ur name to show proof of funds
fourth,u dont need 2 send ur wife's passport datapage,just urs
n lastly,i think u r safe,but 2 b on d safe side,just go to the website
www.cic.gc.ca n check d guide 4 more accurate info.hope this helps
