Yahoo, sorry for replying late. I am on vacation so checking mails/forums intermittently. I have paid the rprf. I hope everything is okay. I am still on vacation outside the country and can not come back until another 2 weeks.
Regarding your question, honestly, I am not sure. I and my friend both applied and he is saying we applied under 2171 but in the tracking sheet I have it as 2174. I have a copy of forms I submitted at home but cant verify it until after my vacation. But, am sure, its between these 2 NOC codes. Hope that helps. I am sure, they are stepping up for november now since few ppl from nov got MR. You will get it soon.
