H4 to H1 or fresh H1b: the safer and easier route

Hi Saurabh,

I am currently working for a US based Entertainment company from India. They have filed an H1b visa for me and hopefully it will make it through the cap. Meanwhile, I have an H4 visa stamped on my passport since my wife has a H1b and is working in US.

The H1b application that has been filed is a fresh H1b and not a COS.

However my question is;

Let’s suppose my H1b petition gets approved in August/Sept.

Is it wiser to:

Travel to the US on the H4 visa and once am there I file a COS to H1b on the already approved petition. N How long does a COS from H4 to H1b usually take.

Or

Get a stamping done in India and start working in US from Oct 1st.

Thanks 4 all ur help.
