Continue H1 or convert to L1

My husband is working with employer A, and I140 is approved, with a priority date of Jan 13, 2013. We are filed in EB3 category. He just received an H1 extension, valid for two years. However, since the wait for priority date to current is long, the plan is to move back to India, and return to US on L1A and pursue EB1c.
On the basis of available data, it looks like waiting for the EB3 to turn current, and taking the L1A visa route and convert to EB1c, might amount to the same timeline. Any suggestions?

Hi @gaurin

EB1C will certainly be faster.

EB3 2013 date will certainly take more than 30 years to get current at current rate with no change in immigration law.
