Hello , I would like to apply for a J - 1 waiver of the 2 year home country requirement . I came into the USA for graduate school 4 years ago and changed my status to J - 1 Research for post graduation work . This was done within the US and I haven't left the US since entering 4 years ago . Does adjusting status within the US from F - 1 to J - 1 Research impact on DOS / USCIS decision to approve a J - 1 waiver ? What are the main issues considered by USCIS in approving a waiver ? Thanks very much in advance for your input .My intention is to apply for a No Objection Statement.
