From the article "Delhi launches doorstep delivery of govt. services" in The Hindu (emphasis mine):
The applicant would have to call 1076 and fix an appointment with a mobile sahayak, who will go to their home and help with filling forms, payment of fees and collection of documents.
This is an excerpt from a reputed newspaper.Can anyone explain me What is the use of "would have to" in this sentence? Can I use "will have to" instead of "would have to"?
