Retention of GC

[vkm98]

My parents got their family-based green cards through me in 2010 with the intention of living here permanently. Since then, there have been some changes and they will be able to stay in the US for only 2 to 4 months in a year.

1) Should they surrender their GCs voluntarily, since they will not be able to stay for majority of the time in US?

2) If they keep the GC, but only stay in the US for 2 to 4 months in a year, will USCIS revoke the GC due to intention of abandonment?

3) If they surrender the GC or it is revoked by USCIS, will there be any issues in using their existing visitor visa (valid till 2105) or a new visitor visa to travel to US?

Thanks

Ideally you should surrender the green card and simultaneously apply for new visitor visa. Their existing visitor visa is no longer valid as their current status is GC.
