Get college coach attention:
Get your UTR up to 12.5+. I heard there was one player on transfer portal that was 12.5 or 12.6 who was contacted by 40+ coaches. Get your UTR up to 11.5+ and you may get contacted by midmajor (MM) coaches but transfers probably dont get a lot of athletic aid unless they are top 3 in lineup level. However, I heard of another player who went on portal as 12.2 and ended up staying at his same college. Risky move tho to ask to be put on portal-might end up with no place to play.
You can get your UTR up by playing prize $ tourneys over winter or summer break that include college players/grads/pros (some of these have qualifiers, some take all applicants), playing Future Qualifiers (some applicants with no ranking points get in as alternates), possibly playing ITA summer circuit at one of the tourneys that attracts 11.5+ player-however you have to have uTR high enough to get in A draw. Playing Future Qualis isnt easy-the #1 D2 player for '19 lost in 1st rd of Qualis of a summer Future-he was UTR 13+. However, he made a lot of $ playing prize $ tourneys. Playing within D2, your UTR may move up slower as there are no D2 players currently ranked 13+. The highest is 12.99. If you dominate wins (allow 4 or less games), you can improve your UTR even if you are playing people with similar UTR to your current UTR.
Power college coaches pull transfers from lower divisions. JUCO #2 from last year transferred to Louisville, won Ohio Valley ITA regional, and will play Oracle Fall Nat Champs with 60 other high level d1 players (plus ITA Cup winner from JUCO, D2, NAIA-D3 winner isnt attending). Guy was UTR 12.38 after his 1st fall tourney-will get to play a lot of 13+s in Newport this week.
BTW junior players dont have to play jr ITF to get D1 coach attention. There are a lot of different UTR earning tourney options in US. Now if you are international outside Europe, maybe your national tourneys did not count for UTR. Know one player who played #2 for a Power 5 top 30 university who didnt play a single jr ITF, never played UsTA nationals, and only played high level sectionals but he went deep in the top sectionals and he also had a close match vs one of that team's top players in the finals of a ITA summer circuit.
Look for prize $ tourneys this Dec or Jan-usually some high level ones in Calif-maybe elsewhere. Check UTR events. If you play well this summer, it's probably too late to transfer for fall 2020. Better to transfer after freshman year-the later you transfer, the more credits that might not transfer. Transfer after freshman year, you might lose a semester of credit. Transfer after soph year- you might lose a whole year of credits. Universities have very different Gen Ed requirements, and many will only give transfers elective credit for some courses. Not all D2 credits will transfer to a D1 university which could be more academically selective.
Most important, give the D2 university a chance! If you go in thinking you dont want to be there, you wont be happy there. Make the most of the opportunity you have been given and that should improve your situation whether you stay or transfer. Remember there is probably some JUCo player who would be happy to take your D2 spot.
