update
Hi Malcolm or anyone else,
Any updates on this? Was your wife able to enter Singapore on the VFTF/96 hour visa? My wife is in the same boat except she is on an US immigration CR1 visa and we have a 20 hour layover in Singapore flying on Singapore Airlines (one way ticket). The other complication is, though we are flying to the US, in addition to Singapore, we also have another layover in Frankfurt, Germany for 6 hours. Not sure if that makes a difference, that we are not flying to the US directly after Singapore, but another short layover and switch to Luftansa.
Please let me know if that worked for you.
Thanks.
