Thx for the informative responses, much appreciated.
So my next question is, what is the difference between prelim and categorical surgery? is categorical just that you are guaranteed a spot all 5 years, where as prelim they cut ppl every year until PGY-5?
And whats the scope for matching into prelim surgery for IMG? Its good right. But categorical its bad?

What is the difference between preliminary, designated and non-designated preliminary and categorical residency positions?
Preliminary: usually 1-2 years of training done at the beginning of your residency period that does NOT lead to board eligibility in general surgery.
Designated preliminary: a position designed or "designated" for an intern who needs 1-2 years of training before going on to a surgical specialty; ie, ortho, ENT, Urology, etc. Many surgical specialties require 1 year of general surgery before embarking on training in the field which leads to board eligibility. Thus, most general surgery programs will designate a certain number of preliminary positions for these candidates; they cannot be filled by non-designated applicants until all the designated positions have been filled.
Non-designated preliminary: a position designed for candidates who are not required to do a surgical internship but rather have to do either surgery or medicine (ie, Anesthesiology, Dermatology); a position designed for candidates interested in general surgery board eligibility but who have failed to either match or otherwise secure a Categorical position (see below).
Categorical: Residency leading to board certification in general surgery (i.e., a 5-year or longer residency).
I am a preliminary surgical intern. Do I have to apply all over again for a position next year?
It depends. If you have a designated position, such as a first year in general surgery in preparation for a residency in Urology/Ortho/ENT etc, you should have matched for your PGY-2 position at the same time you matched into your preliminary year. If you didn't match at that time (during your 4th year) then you will need to either go through the match or find a position outside of the match.
If you have a non-designated 1 year preliminary position you need to try and obtain training for PGY2 and beyond through the match. Even if the program you are currently training at gives you reason to believe they will offer you a position for next year, unless you have it in writing, you need to go through the match again. Programs are not required to give you a contract until April 1 (90 days before the traditional July 1 start of residency) – a long time after the match. If you don't have a contract from them before mid-fall (when applications go in), you must apply or start looking for a position elsewhere.
