Current basically means that the State Department/National Visa Centre is done with the monthly cut-off numbers and it becomes an open field so to speak for anyone else who was selected including the higher case numbers so you don't wait till September to be current.
You'll see on previous visa bulletins for the month of June or after June the word "current" which refers to the above. That means all case numbers/selectees are eligible for an interview subject to the individual having submitted their forms and information.
If June becomes "current" I would expect our 2nd NL to probably come in June itself around the 15th or 20th which means we'd have our interviews in July/August.
It was just 4 months ago I was wondering when April will come and it's here practically. In another 3-4 months it will be crunch time for all of us.
Some DV winners I know personally have told me the interview is the least of your worries if you have the qualifications. The biggest worry is an adequate amount of savings to keep you on your feet whilst you look for a job in America and have to foot all the bills so start saving up
Some people get placed under administrative processing not because of documentation but because the State Department may be worried that these people are a possible public charge. Some go through but some don't because of the administrative processing phase.
Think back to your forms and when it asked how many times you have been to America and all the visas you were issued. What do you think this is? This is telling them if you had the funds to come and go to the US and if you were able to sustain yourself there during your visits i.e. an indication of whether or not you will be a public charge.
Think back to when you were asked on the form what you intend to do in America. What do you think this is? Plenty of people have degrees which meet the vocational requirements but America is technically in a recession and job security is at an all-time low so if you don't have money you need to satisfy them that you can get a job quickly and sustain yourself.
Your case number if you win a green card actually becomes your green card number according to what someone said to me (this person won the DV years ago).
In my case many DV winners I know say I have all the chances to go through (I don't want to celebrate until the fat lady sings) because my company is a registered Federal Government supplier and we do work for organisations such as USAID, ICF, EngenderHealth which are all based out of Maryland and the DC area and also for the IOM which is the biggest migration NGO affiliated to the UN. All my personal trips to the US have been over 6 weeks and I've been there almost 10 or so times and have visas plastered both US and EU plastered all over my passports because of the nature of my work.
My worry isn't even money or starting afresh there. For me the worry is getting that interview and entry visa thats why the waiting game sucks for me more than anything!
