I am going to start my PhD at school A this Fall, meanwhile I want to apply for a few other schools for Fall, 2012, and depending on the outcome, I may want to switch from school A to B after one year.
In my new applications, do I have to mention that I am already attending the PhD program of school A? My guess is I should do so, as in the end I will need to make a sevis transfer request. However, I'm afraid mentioning that I'm attending school A, may have a bad impression, and I'll need to explain why I want to switch in my SOP, etc. This might in the end have adverse effects on my future in either School A, and B; that's to say School B might decide not to take me as I am switching after my arrival, and school A might feel upset about this decision and does not offer any financial assistance anymore. After all, I don't want to lose the option of attending school A unless I become sure I can go to school B, and that presumably wouldn't be sooner than middle of the first year.
I know transferring from one grad school to another is something that many do, but everything seems so mysterious and scary to me...
