I had filed I-730 petition for my Son who is in Nepal. My Case is pending and If I see the processing time it will almost take a year. So is it possible for him to come in Tourist Visa to come USA while his case is pending? Will Applying for the tourist visa affect the petition? If he is granted tourist visa then what can he do over here about his petition? Is there any chance of getting Tourist Visa or it would be better just to wait till the petition gets approved?
