Applying for Hong Kong visit visa from Dubai and receiving the Stamp in Sri Lanka

Currently I'm working in Dubai and when I inquired from the Chines consulate here, they asked me to send my documents directly to Hong Kong immigration for approval. As per them it will take around 1 month.

My concern is by that time, I will be in Sri Lanka. Assuming that I will get the approval, will I be able to get my visa stamped from the Chinese consulate in Sri Lanka?
