Contacting Grad professors for admission/funding
So, I have contacted a few grad professors by email saying on the line of "I read your research paper, and I am very intrigued by XYZ and it aligns with my interests in ABC..and I would like to know if you are looking for a new Ph.D student in your lab in spring 2019." It's been about 3 days, and I haven't gotten any responses. This is actually a hindrance because I have to tailor my statement based on the professors whom I am interested to work with and who has funding to accept a new student.
I don't want to annoy them however...should I give it more time?
