I am a US citizen and plan to sponsor GC for my sister under the F4 category. I would be filing her I-130 but I-485 would be filed after 15-20 years when the Priority Date for F4 category for India becomes current. I have two queries. 1. Would she be able to travel to USA using her B1 tourist visa (which is a non-immigrant visa) during this 15-20 year wait time? 2. If her son decides to apply for higher education in US universities, then would there be any impact on his F1 non-immigrant student visa approval, given that an I-130 was filed for her mother. Could he be denied a visa during his visa interview because the consular officer may see an intent to immigrate ?
