The reason is:
I am trying to find a doctor who would let me not take TB skin test since I am 6 mo. pregnant. No luck yet. So, I am thinking about applying for GC without med exam, then sending it to them whenever they ask.
I thought that I could just send I-130 + supporting forms, then when they approve (I though they'd give me an immigrant number), I will send the app. for a change of status (from H1B) WITH med exam - baby will be born by then. That's why I was asking about I-130. If it doesn't do anything sending it alone, then I am thinking about sending everything without medical papers.
